Description:
------------
The following code does not work. When the nodes in a NodeList that is
the result of an XPath query are copied into an array and returned from
a function. When the nodes in the array are used a warning results:
"Couldn't fetch DOMElement. Node no longer exists..."
Reproduce code:
---------------
bug.php:
<?
$DOMMain =& OpenXMLDoc('main.xml');
$aArray =& GetArray($DOMMain);
echo 'After return: '.$aArray[0]->localName->localName."<br>\n";
function &OpenXMLDoc($sFileName) {
$DOM = new DOMDocument();
$DOM->preserveWhiteSpace = false;
$DOM->load($sFileName);
return $DOM;
}
function &ExecuteXPath($sXPath, DOMDocument &$DOMDocument, DOMNode
&$DOMNode) {
$objXPath = new DOMXPath($DOMDocument);
return $objXPath->query($sXPath, $DOMNode);
}
function &GetArray(&$DOMMain) {
$DOMInclude =& OpenXMLDoc('include.xml');
$NodeImported =
$DOMMain->importNode($DOMInclude->documentElement, true);
$NodeListImported =& ExecuteXPath('./include1', $DOMMain,
$NodeImported);
$NodeListImported = $NodeListImported->item(0)->childNodes;
echo 'In NodeList:
'.$NodeListImported->item(0)->localName."<br>\n";
$aArray = array();
foreach($NodeListImported as $Node) {
$aArray[] = $Node;
}
echo 'In Array: '.$aArray[0]->localName."<br>\n";
return $aArray;
}
?>
main.xml:
<?xml version = "1.0" encoding="ISO-8859-1"?>
<root>
</root>
include.xml:
<?xml version = "1.0" encoding="ISO-8859-1"?>
<include>
<include1>
<div>
<span>test</span>
</div>
</include1>
</include>
Expected result:
----------------
In NodeList: div
In Array: div
After return: div
Actual result:
--------------
In NodeList: div
In Array: div
Warning: Couldn't fetch DOMElement. Node no longer exists in
