### Description

int DomDocument->xinclude ( void )

This function substitutes » XIncludes in a DomDocument object.

Example#1 Substituting Xincludes

`<?php
// include.xml contains :
// <child>test</child>
$xml = '<?xml version="1.0"?>
<root xmlns:xi="http://www.w3.org/2001/XInclude">
<xi:include href="include.xml">
<xi:fallback>
<error>xinclude: include.xml not found</error>
</xi:fallback>
</xi:include>
</root>';
$domxml = domxml_open_mem($xml);
$domxml->xinclude();
echo $domxml->dump_mem();
?>`

The above example will output:

    <?xml version="1.0"?>
    <root xmlns:xi="http://www.w3.org/2001/XInclude">
      <child>test</child>
    </root>

If include.xml doesn't exist, you'll see:

    <?xml version="1.0"?>
    <root xmlns:xi="http://www.w3.org/2001/XInclude">
      <error>xinclude:dom.xml not found</error>
    </root>
