If you mean me, I'm sorry if I come over that way. I'm not really angry, I just get frustrated sometimes because I really want to help people and sometimes they make it so difficult. The advice is quite correct: show a small XML source document, the output you want, and the XSL you have tried. If it didn't work, tell us the symptoms (the incorrect output or the error messages.) This is particularly important for people whose English is poor, because XSLT is a universal language!
(Sometimes though I find it hard to tell the difference between people who are struggling with limited English, and people who are using teenage text slang because they are lazy or think it's cool. Either way, it can be hard to understand. That's no reflection on the present poster.)
