 Marrow,
I really appreciate your reply. I think you have understood what I want. I need to display the latest top 10 discussion topics in HTML which have either the latest reply or latest new topic.
I'm a beginner of XSLT, just started to read Michael Kay's XSLT Programmer's Reference two weeks ago. This is a totally different concept for me from other programming language. I have one question regarding your codes:
<xsl:key name="kDistinctTopic" match="/livelink//llnode"
> use="ancestor-or-self::llnode[last()]/@name"/>
>
My understand is that "descendant-or-self" should be used instead of "ancestor-or-self" as we need to get one lastest children or self llnode from the same topic. If this is true, I also need to change the first "for-each":
> <xsl:for-each select=".//llnode[generate-id() =
> generate-id(key('kDistinctTopic',ancestor-or-self::llnode[last()]/@name)
> )]">
>
Replace "ancestor-or-self" to "descendant-or-self", am I right?
Thanks a lot,
Yan
