RE: Count a substring of an attribute in childnodes
Michael Kay: The second solution is Dimitre's functional programming approach. This is the one that's closest to the way I expressed the problem above. Note that I described a three-stage approach in which stage 2 involves computing some function. This is a classic higher-order function. The three-step algorithm is a function that takes two arguments: the sequence of nodes, and the function to be computed in step 2. Dimitre's FXSL library allows you to write the solution in this form. It takes some getting used to, but it's the most economical way of solving the problem; and although it involves calling the FXSL library, that's written in pure XSLT 1.0 so it should be completely portable. ---
Thank you. I had gotten the notion that FXSL required EXSLT to work.
My recursive solution works, so this is good enough for now, and I have learned something as well.
Thanks to all who took the time to help me. Ragulf Pickaxe :-)
