XInclude is a generic mechanism for merging XML documents, by writing inclusion tags in the "main" document to automatically include other documents or parts thereof.[1] The resulting document becomes a single composite XML Information Set. The XInclude mechanism can be used to incorporate content from either XML files or non-XML text files.
XInclude is not natively supported in Web browsers, but may be partially achieved by using some extra JavaScript code.[2]
For example, including the text file license.txt:
This document is published under GNU Free Documentation License
in an XHTML document:
<?xml version="1.0"?>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:xi="http://www.w3.org/2001/XInclude">
<head>...</head>
<body>
...
<p><xi:include href="license.txt" parse="text"/></p>
</body>
</html>
gives:
<?xml version="1.0"?>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:xi="http://www.w3.org/2001/XInclude">
<head>...</head>
<body>
...
<p>This document is published under GNU Free Documentation License</p>
</body>
</html>
The mechanism is similar to HTML's <object> tag (which is specific to the HTML markup language), but the XInclude mechanism works with any XML format, such as SVG and XHTML.
