I don't see that its good for anyone to advocate anything blindly. Perl is not the only solution, and in some cases, it is the wrong solution. I enjoy programming in Perl too, but I don't want to live next to a nuclear power plant where the control systems are written in Perl.
mirod's point is that there are often solutions to problems with XML other than "just use XSLT". Many of the modules listed above often can handle the problems seen in SOPW. There, people are looking for suggestions or sample code to solve problems that they are running into. He's not blindly advocating Perl as the only solution, he would just like some code from people advocating an XSLT-based solution.
