Yes, that sounds plausible. As a quick hack, I tried adding a destructor to the SimpleXMLElement extension, but that wasn't called either.

I've been playing with that today, and it looks like a workable solution. Thanks for your help! Nick. -- Nick Chalk. Loadbalancer.org Ltd.

Hi Nick, This is most likely a bug in PHP. A deconstructor is called when there are no references left to the object. Since this class uses the libXML library, it is likely that there are still references from the libXML open on the object, which is why it will never be destroyed. Anyway, you should report this bug to the PHP devs (at bugs.php.net). If you really need this, it's probably best to create a class that does not really extend SimpleXMLElement, but you create one inside the constructor, and just forward all function calls to the SimpleXMLElement object you've created in the constructor. - Matijn -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Interesting problem. I would expect it to work too. I assume it is a bug. 2012/7/2 Nick Chalk > Afternoon all. > > I seem to be having a little trouble with extending the > SimpleXMLElement class.
