例子
示例＃1 DOMDocument :: xinclude（）示例
<?php
$xml = <<<EOD
<?xml version="1.0" ?>
<chapter xmlns:xi="http://www.w3.org/2001/XInclude">
<title>Books of the other guy..</title>
<para>
<xi:include href="book.xml">
<xi:fallback>
<error>xinclude: book.xml not found</error>
</xi:fallback>
</xi:include>
</para>
</chapter>
EOD;
$dom = new DOMDocument;
// let's have a nice output
