Read an XML File! Things not included 1. XML Error Checking. The XML could be severely messed up, and the thing could still read it! (or not, depending on how messed up it is!) 2. XML Tag Hunting. You can't go through, find all the tags, then search for the data in the tags. You'd have to know what tags are going to be there, first. ;Got some XML? ;Grab the whole XML file into a string, then use ; XML$( String$, "SectionName",Bit ) ; Where bit goes from 1 -> Number of duplicates.. ;To get internal stats, just keep plonking on section requests. ;The XML$() function can search through 6 iterations. ;You could tweak it if need be, but I doubt any XML files go that deep anyway!

Jayenkai	I code quicker in Blitz because I'm more comfortable with it. I can code in others, but I choose to stick with Blitz, because I'd rather make a working game within a month, than spend 6 months trying to get the basic engine up and running.
