Using PHP to edit an XML file?

[arenlor]

I'm guessing this is possible, just not sure how to do it, I want to simply create an RSS feed which can be updated using a php form online, it would simplify things for me that way, I know how to do RSS too so I don't need that, I just need to know how to edit a page and I can figure it out from there, thanks in advance.

Nevermind I found out how, http://us2.php.net/manual/en/function.fopen.php I just need to do a lot of junk is all, add the RSS feed to a table and then add that info to the write thing, but important is, I'm able to do this on here right?

Moved to Programming forum.

Its easier to use file_get_contents and file_put_contents functions.
