I had to struggle with XSLT to transform XML into HTML a while back. Since it not intended to be a real programming language, I had trouble making it do the equivalent of something basic like iterating through a collection (recursion, ugh!). I can easily see how it would be a highly-paid skill because the lack of debugging tools (again, it is not a real programming language) made me want to curse MSFT and everyone else who were supporting XSLT at the time (way back) as the Second Coming of content publishing. If you ever want a headache, try reading the XSLT spec. http://www.w3.org/TR/xslt http://www.w3.org/TR/xslt
