Subject: Re: [xsl] xsl:key use attribute using string() causes missing all matches except the first one From: Xiaocun Xu <xiaocunxu@xxxxxxxxx> Date: Wed, 24 Mar 2004 11:25:53 -0800 (PST) |
Thanks. I found this reference in the XSLT Programmer's Reference, should have paid more attention when reading :( The reason I was using string() in key was that I am trying to use key grouping with non-existing or empty elements, in particular when there is no subcell element. I realized this does not apply to this case, since my code generates subcell elements only if there are something. thanks, Xiaocun --- David Carlisle <davidc@xxxxxxxxx> wrote: > > > I am not sure what is the reason for > this, would appreciate if anyone could shed light > on > this behavior.
