I am trying to determine if XML is something I can use in place of a mysql database for a small project. It seems very promising for my purposes, but I can't seem to find one piece of information that is necessary for this to work. Is it possible to use a server-side language, like php, to modify the XML document that resides on the server so that users can make changes to the data stored in the file? I'd be surprised if this isn't possible, but I haven't found anything which gives me an answer to this question. Hopefully someone here can help me out. Thanks.
