I hate XSLT

Oh, I hate this so much!!
A variable can't be re-assigned. It's much easier if I can use any other stupid language to parse XML. In my opion, even Basic is much better than this most stupid XSLT parsing. I hope I can prove myself wrong in the future cause looks like there are many fans of this.
But for now, I'll warn anyone who start considering to solve a problem using XSLT: if you just want to parsing XML, then it's fine. But keep in mind if you want to add some extra logic into it, that will definately KILL you. (at least a lot of your time)

summary:
1. difference btw value variable and reference variable, e.g. int and a class
2. difference btw passing by value and passing by reference, this is different than type of variables
