[frank at cleverbridge dot com]

From:             frank at cleverbridge dot com
Operating system: Linux 2.6.12-1.1381_FC3 i686 ath
PHP version:      5.1.3
PHP Bug Type:     *XML functions
Bug description:  cloning Dom Documents or Nodes does not work

Description:
------------
Since 5.1.3 you cannot copy a dom object. References still work. The
implementation of the xml extension seam to have changed.

Reproduce code:
---------------
Since 5.1.3 the following code does not work anymore:

<?php

$dom1 = new DomDocument('1.0', 'UTF-8');

$xml = '<foo />';
$dom1->loadXml($xml);

print "<xmp>\n".$dom1->saveXML()."</xmp>\n";

$node = clone $dom1->documentElement;

$dom2 = new DomDocument('1.0', 'UTF-8');
$dom2->appendChild($dom2->importNode($node->cloneNode(true), TRUE));

print "<xmp>\n".$dom2->saveXML()."</xmp>\n";

$dom3 = clone $dom1;

print "<xmp>\n".$dom3->saveXML()."</xmp>\n";

?>

Expected result:
----------------
<?xml version="1.0"?>
<foo/>

<?xml version="1.0"?>
<foo/>

<?xml version="1.0"?>
<foo/>


Actual result:
--------------
&lt;?xml version="1.0"?&gt; &lt;foo/&gt;
