Subject: Re: [xsl] grouping based on string but with child nodes From: "G. Ken Holman" <gkholman@xxxxxxxxxxxxxxxxxxxx> Date: Mon, 13 Oct 2008 11:40:49 -0400 |
Yes, use 2 passes, it will help you diagnose problems in the 2nd pass much more easily.
The first pass is an idenity transform with:
<xsl:template match="title"> <xsl:for-each select="tokenize(., '||')> <title><xsl:value-of select="."/></title>
I have some old EAD XML that I'm trying to convert to a slightly better form and what I want to take is something like this: ... So desired output (in a variable ... I've been assuming that this is a two-pass problem where I have to replace the '||' with some empty XML element and then group-by that element?
If that is the case what is the best way to replace these for grouping?
Or is it possible to do this all-in-one?
XSLT2 solution obviously desired to avoid too much recursion. :-)
