Ok, I have just lodged a ticket with the hosting company asking if there are any plans of upgrading to php5 in the near future, but i don't like my chances. (for the record i didn't organise hosting)
I have been looking into using xml_parse but have run into issues when opening and closing tags are on seperate lines or when there is a tag like: <itunes:category text="Information Technology"/>
Does anyone know if there is a class or function out there already the can do what simplexml_load_string does, but in php4?
