Dumping DOMDocument doesn't really work

[adrianbj]

Version: 2.5.2

Bug Description

Dumping a DOMDocument object results in basically an empty dump

Steps To Reproduce

Notice the difference in output for a Tracy dump call vs a print_r

Expected Behavior

I would expect to see a nested dump of object properties

Possible Solution

Sorry, I haven't investigated :)

It is PHP problem (related to this https://bugs.php.net/bug.php?id=48527) and I don't know how to solve it.

Interesting that in the linked issue: https://bugs.php.net/bug.php?id=65565 it is mentioned that it has been fixed. I am running 7.2 here and it's still an issue.

Oh well, not a big deal. Thanks for the link.

It seems that only var_dump() was fixed.

Ah yes - sorry, I didn't read it thoroughly enough.

My workaround ...

Tracy\Dumper::$objectExporters[\DOMNode::class] = function ($obj) {
	$dump = print_r($obj, 1);
	preg_match_all('~^\s*\[([^\]]+)\]\s+=>\s*(\S*)\s*$~m', $dump, $aMatches);
	return array_combine($aMatches[1], $aMatches[2]);
};
