Bug description: DOM object custom variables get lost
Description:
------------
Setting custom variables in DOM objects like:
$domNode->customVar = 'myValue';
Are inconsistently lost when working with a dom.
Reproduce code:
---------------
<?php
class myclass {
function run() {
$xp = new domxpath($this->dom);
$widths = $xp->query('//td/@width');
foreach ($widths as $width) {
echo $this->name.' 1: width->myVar
value:'.$width->myVar.'<br>';
$width->myVar = '1';
}
$tds = $this->dom->getElementsByTagName('td');
foreach ($tds as $td) {
echo $this->name.' 2: td->myVar value:'.$td->myVar.'<br>';
$td->myVar = '1';
}
echo '<br>';
$tds = $this->dom->getElementsByTagName('td');
foreach ($tds as $td) {
if ($width = $td->getAttributeNode('width')) {
echo $this->name.' 3: width->myVar
value:'.$width->myVar.'<br>';
$width->myVar = '2';
}
echo $this->name.' 4: td->myVar value:'.$td->myVar.'<br>';
$td->myVar = '2';
}
echo '<br>';
}
}
$xml = '<root>
<tr><td width="40">hello</td><td
width="40">world</td></tr>
<tr><td>Just one TD</td></tr>
<tr><td>TD with <b>mixed</b>
<i>content</i></td></tr>
</root>';
$dom = new DomDocument;
$dom->loadXML($xml);
$firstInstance = new myclass;
$firstInstance->name = 'firstInstance';
$firstInstance->dom = $dom;
$firstInstance->run();
$secondInstance = new myclass;
$secondInstance->name = 'secondInstance';
$secondInstance->dom = $firstInstance->dom;
$secondInstance->run();
?>
Expected result:
----------------
firstInstance 1: width->myVar value:
firstInstance 1: width->myVar value:
firstInstance 2: td->myVar value:
firstInstance 2: td->myVar value:
firstInstance 2: td->myVar value:
firstInstance 2: td->myVar value:
firstInstance 3: width->myVar value:1
firstInstance 4: td->myVar value:1
firstInstance 3: width->myVar value:1
firstInstance 4: td->myVar value:1
firstInstance 4: td->myVar value:1
firstInstance 4: td->myVar value:1
secondInstance 1: width->myVar value:2
secondInstance 1: width->myVar value:2
secondInstance 2: td->myVar value:2
secondInstance 2: td->myVar value:2
secondInstance 2: td->myVar value:2
secondInstance 2: td->myVar value:2
secondInstance 3: width->myVar value:1
secondInstance 4: td->myVar value:1
secondInstance 3: width->myVar value:1
secondInstance 4: td->myVar value:1
secondInstance 4: td->myVar value:1
secondInstance 4: td->myVar value:1
Actual result:
--------------
firstInstance 1: width->myVar value:
firstInstance 1: width->myVar value:
firstInstance 2: td->myVar value:
firstInstance 2: td->myVar value:
firstInstance 2: td->myVar value:
firstInstance 2: td->myVar value:
firstInstance 3: width->myVar value:1
firstInstance 4: td->myVar value:
firstInstance 3: width->myVar value:1
firstInstance 4: td->myVar value:
firstInstance 4: td->myVar value:
firstInstance 4: td->myVar value:
secondInstance 1: width->myVar value:
secondInstance 1: width->myVar value:
secondInstance 2: td->myVar value:
secondInstance 2: td->myVar value:
secondInstance 2: td->myVar value:
secondInstance 2: td->myVar value:
secondInstance 3: width->myVar value:1
secondInstance 4: td->myVar value:
secondInstance 3: width->myVar value:1
secondInstance 4: td->myVar value:
secondInstance 4: td->myVar value:
secondInstance 4: td->myVar value:
