Online W3C XML Schema Validator , Microsoft, 2002-10-11
An online HTML form-based interface for validating schemas (XSD & XDR) and instance documents using the System.Xml.XmlValidatingReader in the .NET framework [appears to have been withdrawn as of 2006-12]
XML ValidatorBuddy is commercial software for the Microsoft Windows platform for editing and validating large XML and JSON documents.
This Perl module allows you to validate XML documents against a W3C XML Schema. This module does not implement the full W3C XML Schema recommendation, but a useful subset. See the SCHEMA SUPPORT section in the module documention.
You can install XML::Validator::Schema from CPAN, or download it from SourceForge: http://sourceforge.net/project/showfiles.php?group_id=89764

xnsdoc 1.2 is now available, a professional tool to generate documentation of W3C XML-Schema in a JavaDoc-like visualization.
xnsdoc supports all common schema design practices like chameleon, russian doll, salami slice, venetian blind schemas or circular schema references.
xnsdoc can be used from the command line, as an Apache Ant Task, as an Apache Maven Plugin, as an eclipse plugin or integrated as a custom tool in many XML development tools.
Release 1.2 fixes all known bugs and comes with improved integration into eclipse, Apache Maven and Apache Ant.
You can download a free trial version at http://www.buldocs.com/xnsdoc/download/
XS3p is a schema documentation generator developed by Zar Zar Tun at DSTC. Basically, it is an XSLT stylesheet that will generate an XHTML document from an XSD schema. Some of its cool features are:
DSTC no longer exists, and the original homepage for this tool is gone. Both oXygen and Stylus Studio appear to use it, and search engines can locate copies of the stylesheet and, in some cases, the license without which it cannot legally be used.
XmlPlus xsd2cpp is an open-source tool which provides XML data binding for C++ through XML Schema. The xsd2cpp tool is a C++ code generator. The xsd2cpp tool when invoked on an input XML Schema, generates C++ classes(headers) mapped to the input XML Schema components. Alongside, wherever needed, it generates implementation files(.cpp) for the generated C++ classes. Also, a sample application(main.cpp) is generated to demonstrate how an application could consume the generated C++ source files.
XSDBench XML Schema Benchmark 1.0.0 released Boris Kolpackov 2006-10-18
XSDBench is an open-source W3C XML Schema benchmark that compares the performance of validating XML parsers. It measures validation throughput, statically-linked test executable size, and, where possible, peak heap and stack memory usage during parsing. The following parsers are supported in the latest release:
More information on the benchmark architecture, results, as well as the benchmark source code are available from http://www.codesynthesis.com/projects/xsdbench
XSD from examples , Microsoft, 2002-12-14
We would like to announce the availabitlity of Microsoft XSD Inference Beta 1 tool. The Microsoft XSD Inference utility is used to create an XML Schema definition language (XSD) schema from an XML instance document. When provided with wellformed XML file, the utility generates an XSD that can be used to validate that XML file. You can also refine the XSD generated by providing the tool more well-formed XML files. You can get the binaries and documentation from http://www.gotdotnet.com/team/xmltools/
XSD/e 1.1.0 - validating XML parser generator for embedded systems Boris Kolpackov 2007-09-20
CodeSynthesis XSD/e is an open-source XML parser generator for mobile and embedded systems. It provides event-driven, stream-oriented XML parsing, XML Schema validation, and C++ data binding while maintaining small footprint and portability.
Compared to general-purpose validating XML parsers, the XSD/e-generated parsers are 2-10 times faster while maintaining the lowest static and dynamic memory footprints. For example, a validating parser executable can be as small as 120KB in size. XSD/e is also highly-portable and can be used without STL, RTTI, iostream, C++ exceptions, and C++ templates.
xframe - xsddoc 0.8-beta released , Kurt Riede, 2005-05-22.

XSD regex-> Java 1.4 regex , James Clark 2002-04-30
I've written some Java code that translates from the syntax of XSD regexes to the syntax of JDK 1.4 java.util.regex regexes. The source, binaries and documentation can be downloaded from: [ http://www.thaiopensource.com/download/xsdregex-20020430.zip ]
I am releasing it under a very liberal license (the BSD license), which makes it free even for commercial use.
xsd - a W3C XML Schema to C++ translator Boris Kolpackov 2005-10-08
xsd is a cross-platform, open source W3C XML Schema to C++ translator. It supports two C++ mappings: in-memory C++/Tree and event-driven C++/Parser.
The C++/Tree mapping consists of data types that represent the given vocabulary, a set of parsing functions that convert XML instance documents to a tree-like in-memory data structure, and a set of serialization functions that convert the in-memory representation back to XML.
The C++/Parser mapping provides parser templates for data types defined in XML Schema. Using these parser templates you can build your own in-memory representations or perform immediate processing of XML instance documents.
Details and download from http://codesynthesis.com/products/xsd/
The xsdvalid distribution contains the XML Schema validation engine that will be integrated into the future XMLmind XML Editor product ( http://www.xmlmind.com/xmleditor/ ).
This engine has been made available to schema and DTD authors in the form of 3 command-line tools:
The xsdvalid distribution can be downloaded from [ http://www.xmlmind.com/xvalid.html ] .

Note that there is no longer an XML Schema Working Group to monitor issues or pull requests.
As part of the process of getting XML Schema to Recommendation, a draft Type Library is available, with definitions of complex types attempting to cover many common needs, including general text content, arrays, complex numbers and dimensioned quantities.
Richard Tobin and Henry S. Thompson have posted a first cut at an XML serialisation of the (PSV) Infoset .
The W3C has launched a Test Collection Initiative to help XML Schema processor implementors.
XML Schema Part 0: Primer
XML Schema Part 0: Primer is a non-normative document intended to provide an easily readable description of the XML Schema facilities, and is oriented towards quickly understanding how to create schemas using the XML Schema language. XML Schema Part 1: Structures and XML Schema Part 2: Datatypes provide the complete normative description of the XML Schema language. This primer describes the language features through numerous examples which are complemented by extensive references to the normative texts.

Referencing xml schemas and dtds.
Your XML file may reference an external XML schema (XSD) or DTD file, for example:
If the referenced URL or the namespace URI is not recognized, it's marked as an error. To solve the problem:
Place the caret at the referenced URL and press Alt+Enter .
From the list of suggested options, select one of the following:
Fetch external resource . IntelliJ IDEA downloads the referenced file and associates it with the URL (or the namespace URI). The error highlighting disappears. The XML file is validated according to the downloaded schema or DTD. (The associations of the URLs and the namespace URIs with the schema and DTD files are shown on the Schemas and DTDs page in the Settings dialog.)
Manually set up external resource . Use this option when you already have an appropriate schema or DTD file available locally. The Map External Resource dialog will open, and you'll be able to select the file for the specified URL or namespace URI (for example, http://www.example.org/xsds/example.xsd or http://www.example.org ). The result of the operation is the same as in the case of fetching the resource.
Ignore external resource . The URL or the namespace URI is added to the list of Ignored Schemas and DTDs. (This list is shown on the Schemas and DTDs page in the Settings dialog.) The error highlighting disappears. IntelliJ IDEA won't validate the XML file, however, it will check if the XML file is well-formed.
Add Xsi Schema Location for External Resource . This intention action lets you complete your root XML elements. If the namespace is already specified, IntelliJ IDEA can add a couple of missing attributes.
For example, if you have a fragment like this:
and you invoke the Add Xsi Schema Location for External Resource intention action on the value of the xmlns attribute, the result will be:
At this step, you can add the schema URL, and then map the URL (or the namespace URI) onto an appropriate schema file, or add the URL (or the URI) to the list of Ignored Schemas and DTDs.
If you previously created an XML Map , you can use it to import XML data into cells that are mapped, but there also are several methods and commands for importing XML data without an XML Map.
If you have an XML Map, do this to import XML data into mapped cells:
In the XML Map, select one of the mapped cells.
Click Developer > Import .
If you don't see the Developer tab, see Show the Developer tab .
In the Import XML dialog box, locate and select the XML data file (.xml) you want to import, and click Import .
Import an xml data file as an xml table, import multiple xml data files, import multiple xml data files as external data, open an xml data file to import its data.
For more information about issues, see Common issues with importing XML data at the end of this article.
If the XML data file doesn't refer to a schema, Excel infers the schema from the XML data file.
In the Import Data dialog box, do one of the following:
Select XML table in existing worksheet to import the contents of the XML data file into an XML table in your worksheet at the specified cell location.
Select XML table in new worksheet to import the contents of the file into an XML table in a new worksheet starting at cell A1. The schema of the XML data file is displayed in the XML Source task pane.
If the XML data file doesn't refer to a schema, then Excel infers the schema from the XML data file.
To control the behavior of XML data (such as data binding, format, and layout), click Properties , which displays the XML Map properties dialog box. For example, existing data in a mapped range will be overwritten when you import data by default, but you can change this.
Select a mapped cell to import multiple XML files into a single set of mapped cells.
If you want to import multiple XML files into multiple sets of mapped cells, click a cell anywhere on the worksheet that isn't mapped.
In the Import XML dialog box, locate and select the XML data file (.xml) you want to import.
If the files are contiguous, press Shift, and click the first and the last file in the list. All of the data from the XML files will be imported and appended to the mapped cells.
If the files aren't contiguous, press and hold Ctrl, and click each file you want to import in the list.
Click Import .
If you selected files that aren't contiguous, the Importing <filename>.xml dialog box appears. Select the XML Map that corresponds to the XML data file you're importing for each file.
To use a single map for all of the selected files that aren't yet imported, select Use this XML Map for all selected files of this schema .
To import multiple XML files that use the same namespace but different XML schemas, you can use the From XML Data Import command. Excel creates a unique XML Map for each XML data file you import.
Note: If you're importing multiple XML files that don't define a namespace, these XML files are treated as if they use the same namespace.
If you're using Excel with a Microsoft 365 subscription, click Data > Get Data > From File > From XML .
If you're using Excel 2016 or earlier, click Data > From Other Sources > From XML Data Import .
Go to the drive, folder, or Internet location that has the XML data file (.xml) you want to import.
Select the file and click Open .
XML table in existing worksheet The contents of the file are imported into a new XML table in a new worksheet. If the XML data file doesn't refer to a schema, Excel infers the schema from the XML data file.
Existing worksheet The XML data is imported in a two-dimensional table with rows and columns that shows XML tags as column headings, and data in rows below the column headings. The first element (the root node) is used like a title and is displayed in the specified cell location. The rest of the tags are sorted alphabetically across the second row. In this case, Excel doesn't infer a schema, and you can't use an XML Map.
New worksheet Excel adds a new worksheet to your workbook and automatically puts the XML data in the upper-left corner of the new worksheet. If the XML data file doesn't refer to a schema, Excel infers the schema from the XML data file.
To control the behavior of XML data, such as data binding, format, and layout, click Properties , which displays the XML Map properties dialog box. For example, existing data in a mapped range is overwritten when you import data by default, but you can change this.
Click File > Open .
In the Open dialog box, click the drive, folder, or Internet location that has the file that you want to open.
If the Import XML dialog box appears, the file you opened refers to one or more Extensible Stylesheet Language Transformation (XSLT) style sheets, so you can click one of the following options:
Open the file without applying a style sheet The XML data is imported in a two-dimensional table with rows and columns that shows XML tags as column headings, and data in rows below the column headings. The first element (the root node) is used like a title and is displayed in the specified cell location. The rest of the tags are sorted alphabetically across the second row. In this case, Excel doesn't infer a schema, and you can't use an XML Map.
Open the file with the following style sheet applied (select one) Select the style sheet that you want to apply, and then click OK . The XML data is formatted according to the style sheet that you selected.
Note: The XML data is opened as read-only in Excel so that you don't accidentally save your original source file in the Excel Macro-Enabled Workbook file format (.xlsm). In this case, Excel doesn't infer a schema, and you can't use an XML Map.
If the Open XML dialog box appears, the XML file doesn't have any XSLT style sheet references. To open the file, click one of the following options:
Click As an XML table to create an XML table in a new workbook.
The contents of the file are imported into the XML table. If the XML data file doesn't refer to a schema, Excel infers the schema from the XML data file.
Click As a read-only workbook .
The XML data is imported in a two-dimensional table with rows and columns that shows XML tags as column headings, and data in rows below the column headings. The first element (the root node) is used like a title and is displayed in the specified cell location. The rest of the tags are sorted alphabetically across the second row. In this case, Excel doesn't infer a schema, and you can't use an XML Map.
The XML data is opened as read-only in Excel so that you don't accidentally save your original source file in the Excel Macro-Enabled Workbook file format (.xlsm). In this case, Excel doesn't infer a schema, and you can't use an XML Map.
Click Use the XML Source task pane .
The schema of the XML data file is displayed in the XML Source task pane. You can then drag elements of the schema to the worksheet to map those elements to the worksheet.
Excel displays the XML Import Error dialog box when it can't validate data according to the XML Map. In this dialog box, click Details for additional information about each error. The following table lists some common import errors:
The XML file you're trying to open doesn't refer to an XML schema. To work with the XML data that's in the file, Excel needs a schema based on the contents of the XML file. If that schema is incorrect or insufficient, remove it from your workbook. Then create an XML schema file and edit the XML data file so that the XML data file refers to the schema. For more information, see Map XML elements to cells in an XML Map .
Note: You can't export the Excel inferred schema as a separate XML schema data file (.xsd). Although there are XML schema editors and other methods for creating an XML schema file, you may not have convenient access to them or know how to use them.
Follow these steps to remove the schema that Excel created from your workbook:
Click Developer > Source .
In the XML Source task pane, click XML Maps .
In the XML Maps dialog box, click the XML Map Excel created, and click Delete .
When you work with multiple XML data files and XML schemas, you typically create an XML Map for each schema, map the elements you want, and then import each XML data file to the appropriate XML Map. Using the Import command to open multiple XML files with the same namespace, you can only use one XML schema. When you use this command to open multiple XML files that use the same namespace but different schemas, you can get unexpected results. For example, data may get overwritten, or the files won't open.
To import multiple XML files that use the same namespace but different XML schemas, try use the From XML Data Import command (click Data > From Other Sources ). This command allows multiple XML files with the same namespace to use multiple XML schemas. Excel creates a unique XML Map for each XML data file you want to import.
If you don't see the Developer tab, do the following to display it:
In Excel 2013 and Excel 2010:
Click File > Options .
Click the Customize Ribbon category.
Under Main Tabs , check the Developer box, and click OK .
In Excel 2007:

The XML editor lets you create an XML Schema definition language (XSD) schema from an XML document. The XML file determines how the schema is generated in the following manner:
If the XML document has no schema or Document Type Definition (DTD) associated with it, the data in the XML document is used to infer a new XML Schema.
If the XML document contains an associated DTD, the external DTD and internal subset are converted to a corresponding XML Schema.
If the XML document contains an inline XML-Data Reduced (XDR) schema, the XDR schema is converted to a corresponding XML Schema.
The schemas that are created are then used to provide IntelliSense for the XML file.
For more information about the schema inference engine, see Infer an XML schema .
Open an XML file in Visual Studio.
On the menu bar, choose XML > Create Schema .
An XML Schema document is created and opened for each namespace found in the XML file. Each schema is opened as a temporary miscellaneous file. The schemas can be saved to disk, added to your project, or discarded.

@DavidDoria: By specifying of the XML Schema of <employee> we set schema for all it's children (for example <firstname> or <lastname>).Typically one set xmlns and schemaLocation for the root element of the XML file only. The example in my answer is very short. Typically one would have <employees> for example as root element with many <employee> children. In the way one would define one schema ...
Add one more slash after file:// in the value of xsi:schemaLocation. (You have two; you need three. Think protocol://host/path where protocol is 'file' and host is empty here, yielding three slashes in a row.) You can also eliminate the double slashes along the path.
You can manipulate your Schema with the XML DOM. You can transform your Schema with XSLT. XML Schemas are extensible, because they are written in XML. With an extensible Schema definition you can: Reuse your Schema in other Schemas. Create your own data types derived from the standard types. Reference multiple schemas in the same document.
Referencing an XML Schema. A XML Schema can be referenced from an XML document by defining the schemaLocation and noNamespaceSchemaLocation attributes. The 'schemaLocation' attribute is used to reference XML Schema(s) that are defined in a target-namespace.
An XML schema, commonly known as an XML Schema Definition (XSD), formally describes what a given XML document can contain, in the same way that a database schema describes the data that can be contained in a database (i.e. table structure, data types, constraints etc.). The XML schema defines the shape, or structure, of an XML document, along ...
The XML Schema model is more like a programming language where you bind variables to formal type definitions. The xsd:complexType allows you to define the type of an element, which conveys its structure. Nesting xsd:complexType within the element declaration effectively binds it to that element (like a variable).
Reference the XSD schema in the XML document using XML schema instance attributes such as either xsi:schemaLocation or xsi:noNamespaceSchemaLocation. Add the XSD schema file to a schema cache and then connect that cache to the DOM document or SAX reader, prior to loading or parsing the XML document. The following sections demonstrate each of ...
XML Schema 1.1Status. XML Schema 1.1 (in two parts) is a W3C Recommendation. It is intended to be mostly compatible with XML Schema 1.0 and to have approximately the same scope, but also to fix bugs and make whatever improvements we can, consistent with the constraints on scope and compatibility.
The following example is a DTD file called "note.dtd" that defines the elements of the XML document above ("note.xml"): The first line defines the note element to have four child elements: "to, from, heading, body". Line 2-5 defines the to, from, heading, body elements to be of type "#PCDATA".
In This Section. Discusses the Schema Object Model (SOM) in the System.Xml.Schema namespace that provides a set of classes that allows you to read a Schema definition language (XSD) schema from a file or programmatically create a schema in-memory. Discusses the XmlSchemaSet class that is a cache where XSD schemas can be stored and validated.
Now we want to create a schema for the XML document above. We start by opening a new file that we will call "shiporder.xsd". To create the schema we could simply follow the structure in the XML document and define each element as we find it. We will start with the standard XML declaration followed by the xs:schema element that defines a schema:
The central motivation for moving to XML Schema based configuration files was to make Spring XML configuration easier. The 'classic' <bean/>-based approach is good, but its generic-nature comes with a price in terms of configuration overhead.. From the Spring IoC containers point-of-view, everything is a bean. That's great news for the Spring IoC container, because if everything is a bean ...
The XML file is validated according to the downloaded schema or DTD. (The associations of the URLs and the namespace URIs with the schema and DTD files are shown on the Schemas and DTDs page in the Settings dialog.) Manually set up external resource. Use this option when you already have an appropriate schema or DTD file available locally.
Learn how to use the <schema> element in XML Schema Definition (XSD) to define the structure and constraints of an XML document. The <schema> element is the root element of every XSD file and contains other elements and attributes. W3Schools provides examples and tutorials on XML Schema and other XML topics.
If you have an XML Map, do this to import XML data into mapped cells: In the XML Map, select one of the mapped cells. Click Developer > Import.

To create an XML schema. Open an XML file in Visual Studio. On the menu bar, choose XML > Create Schema. An XML Schema document is created and opened for each namespace found in the XML file. Each schema is opened as a temporary miscellaneous file. The schemas can be saved to disk, added to your project, or discarded.
In an XML document, you cannot hint that a single XML document instance must simultaneously adhere to multiple XSDs (other than for separate namespaces). You could, however, validate sequentially once per XSD you wish to apply to the XML.
