This example works... adapt to your needs. (Sorry for the delay)
<?php
$xml = "
<item>
<name>John</name>
<file>file1.xml</file>
<x>Foobar</x>
</item>
<item>
<name>Bob</name>
<file>file2.xml</file>
<x>Something</x>
</item>
<item>
<name>George</name>
<file>file3.xml</file>
<x>Gotcha</x>
</item>
";
$file = 'file2.xml';
function callback($matches)
{
global $file;
if(strpos($matches[1],$file) === FALSE)
{ return $matches[0]; }
else
{ return ''; }
}
$new_xml = preg_replace_callback('|<item>(.*)</item>|Usi','callback',$xml);
echo nl2br(htmlentities($xml));
echo "<hr>";
echo nl2br(htmlentities($new_xml));
?>
