Bug description: DOMDocument::removeChild corrupts node
Description:
------------
Using DOMDocument::removeChild corrupts node in the document in some
cases.
Given a node $node and removing a parent node of this node renders $node
unusable (properties are gone, but $node is still of class DOMElement).
Reproduce code:
---------------
<?php
// This works as expected
$dom = DOMDocument::loadXML('<root><child/></root>');
$xpath = new DOMXpath($dom);
$node = $xpath->query('/root')->item(0);
echo $node->nodeName . "\n";
$dom->removeChild($GLOBALS['dom']->firstChild);
echo "nodeType: " . $node->nodeType . "\n";
echo "nodeName: " .$node->nodeName . "\n";
echo "parentNode: " .$node->parentNode . "\n";
// This breaks "$node"
$dom = DOMDocument::loadXML('<root><child/></root>');
$xpath = new DOMXpath($dom);
$node = $xpath->query('//child')->item(0);
echo $node->nodeName . "\n";
$GLOBALS['dom']->removeChild($GLOBALS['dom']->firstChild);
echo "nodeType: " . $node->nodeType . "\n";
echo "nodeName: " .$node->nodeName . "\n";
echo "parentNode: " .$node->parentNode . "\n";
echo "\n";
?>
Expected result:
----------------
Properties of $node should still exists, see part1:
root
nodeType: 1
nodeName: root
parentNode:
Actual result:
--------------
Properties are gone
child
