 I have been doing XSLT for about four years now and this input XML has me a little stumped as to how to implement. I believe I am using Xalan 2.6 (bundled as part of an EMC Documentum product called WebPublisher) and the only version it supports currently is XSLT 1.0. This is a particularly difficult problem for XSLT 1.0 because of the organization of the grouping. Here is the XML input: I, too, had to use recursive logic to address this. A complete solution is below. As I've often posted, I'm using variables for grouping because of the sub-document context (keys have document-wide context in XSLT 1.0 but can be accessed in a limited fashion in XSLT 2.0). What was interesting is the organization of your headers ... I made the assumptions that the order is critically important: it isn't just that the headers are the same, but that the same headers are in the same relative position to each other as children of FAQs. I hope the code below helps ... the output matches your requirement. . . . . . . . . . . Ken T:\ftemp>type cindy.xml
