If you're doing heavy "database" type queries, then just use mySQL. XML is kind of a PITA to use IMHO. You have to set up DOM Objects and all this crap, then loop over nodes and use xpaths and watch out for #text elements and it's just messy. I'm forced to use XML for part of a project @ work, and I'm always grateful when I can switch back to using a database and SQL as God intended it to be. ;-p However, if you're just storing some basic configs or preferences, then I would suggest looking into a much simpler (and universal): http://www.php.net/parse_ini_file -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
