Wow, that's the fourth time this question has been asked in two days. Does no-one lurk before posting questions nowadays? Standard XSLT doesn't allow you to access variables in this way any more than C or Java do. It's not an introspective language. Some products (Saxon, Xalan) have an xx:evaluate extension that lets you do it. However, it's usually the wrong thing to do. If you have three variables a, b and c and you don't know statically which one you want, then you should probably have a single variable X whose value is an XML tree containing a, b, and c as elements. You can then access the elements using standard path expressions - including the dynamic form //*[name()=$var].
