Re[4]: [xsl] Highlighting words/phrases

---

---

I figured it out - the xsl:copy command in the text() template was
mucking up the works - I took it out, and it works fine.



CG> Hi.

CG> I thought I had everything working wonderfully - Alexander Johannesen's
CG> highligher template helped alot - thanks, Alexander!

CG> However, I'm having mixed-content problems.

CG> I originally called the highlighter template from the element templates (p, for
CG> example), but that either lost the child element tags, or put the tags
CG> and content in the wrong place. Then I tried calling it from the template
CG> matching text() (which I thought was working last night, but is no
CG> longer working today), and now it doesn't catch the word at all.

CG> Is there a solution I'm not seeing?

CG> Thanks,
CG> Cindy
