Use some XML module if you want to create real XML data easy.

You can use XML::Simple (that works with XML::Parser), or XML::Smart (that works with XML::Parser or with it own Parser too).

I prefer to use XML::Smart since you don't need to install an extra module for the parser, and works like XML::Simple, but with some extra resources. But I'm also the author of XML::Smart and my opinion don't count much in this case. ;-P
