Hi Chris, I remember having this problem, when I used the same version of Cocoon one year ago. I'm not 100% sure, but I mean fn:replace is a function belonging to XPath 2.0 [1] and Cocoon 2.1.11 integrates a Xalan implementing XPath 1.0 only. You should check which version of Xalan do you use and be sure this version implements XPath 1.0 only.
I guess there are some ways to use a more up-to-date Xalan (implementing XPath 2.0), but if I well remember I used another workaround. I'm no more sure which one, but I guess you should find enough interesting transformers [2]. It is not the best way, but it is possible to have a "heavy" two-passes mechanism. At first xslt transformer adding JX instructions (like 'if test' or 'set var' and variable instantiations) in the right places and then a JX transformer evaluating JX instructions (like removing 'if test' with a false condition or removing/evaluating 'set var' in order to instance these variables in another places). I hope it will help. Good luck. Please give us your feedback about these ideas. Thomas.
