Description:

Elements of the array returned by xpath() cannot be deleted.
I can change those elements, but deleting is impossible.

How can I delete a node returned by xpath()? Is there a way to find out where the node I found is within the whole xml tree?

Thanks, G?nther.

Reproduce code:
---------------
<?php
$xmlstr = <<<XML
<?xml version='1.0' standalone='yes'?>
<root>
 <movie>Movie One</movie>
 <movie>Movie Two</movie>
</root>
XML;

$xml = new SimpleXMLElement($xmlstr);

$movs = $xml->xpath('//movie');

// Trying to delete the reference returned by xpath
unset($movs[0]);

// $movs[0] = NULL; doesn't work either

// No changes
echo $xml->asXML();

?>


Expected result:
----------------
<?xml version="1.0" standalone="yes"?>
<root>
 <movie>Movie Two</movie>
</root>

Actual result:
--------------
<?xml version="1.0" standalone="yes"?>
<root>
 <movie>Movie One</movie>
 <movie>Movie Two</movie>
</root>
