Xml: displaying it and modifying it

He kirupeans, I hope all is good. I have an xml file that I want to be able to display it nicely formatted in xhtml or anything else as long as its viewable in the browser. At the same time I need to be able to modify, add, delete items in that list. This would actually rewrite the xml file.

So far Ive found about xslt, that is used to style xml. The main disadvantage of this is that it only works in Internet explorer. And then for the rewriting Im thinking about using php. To be honest, Im having trouble figuring out how to rewrite the xml file with php, it seems like its going to be a nightmare…although Im willing to do whatever it takes.

So I came here to kirupa land to see if anybody can give me a better solution than xslt and php, or maybe you guys know of some good tutorials I can read where these topics are addressed. Any suggestions will be appreciatted.
