I'd suggest opening the file in smaller chunks, if poss. It looks to =20
me like your XML file is huge, and is being loaded in all at once.

As a first step, you could try the inbuilt simplexml_load_file ( =20
http://uk.php.net/simplexml_load_file ) directive, which might give =20
you some more clues.
