Bug description: Results from xpath() cannot be deleted
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, Günther.
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>
