Array/Objectto/from XML in php4?

[sid]

I am working on an application, that uses XML for data transfer between 2 servers. It's all working nicely - getting my "interface" object populated works like a charm - however, now that I wanted to test the application on the production server (PHP 4.4.4 - development server is 5.1), I of course, ran into a ton of issues due to php4's lack of XML support (compared to v5). After having tried multiple classes and trying to shimmy something together myself, I am somewhat frustrated and out of ideas.

does anybody out there know of a class that allows to convert (associative & max. 2-dimensional) arrays to (and from) XML in a php4 environment?

thanks a bunch in advance!

For cases where XML data is small enough to be loaded entirely into memory, I've used keith devens xml lib.
