[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Re: XSLT 1.0: Grouping Adjacent Elements in Embedded
 Sorry to do it this way, but it was easier for me to rewrite the script than to debug it. I have once build a stylesheet that converts mapping rules into a xsl. This mapping definition contained a command to gather sequences of elements into a wrapper element. It is related to the sort grouping problem, but that doesn't help you if you have to interfere the wrapping at the encounter of a certain element and continue it afterwards. Anyhow, I conceived some nice methods to just do the trick you are trying to do. In your case the code would look like the following. Note that I have wrapped you initial dataset in a DATA element. Msxsl seems to give the correct output. Grtz, Geert <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <!--+ ==============================================================
