IE problem - I need help with xmlhttprequest and parsing xml

[admin]

Hello.

What i'm trying to do is load a simple xml/rss -feed by using XMLHttprequest and the access the object and write out the content.


It now works in Firefox but for some reasong it doesn't work in IE though it should. It gives no errors or anything - it just doesn't anything in IE. I know this technique works in IE but i'm doing something wrong.

Any help with that??
