Subject: Re: [xsl] XSLT/XPath Question (Grouping Authors by First Character of Last Name) From: "Kevin Grover" <kevin@xxxxxxxxxxxxxxx> Date: Sun, 4 Mar 2007 12:41:42 -0800 |
It also seems that this may have answered my other question: about saving the list of letters so I can iterate over them later (to make links to the TOC entries. It looks like I can just take the main for-each loop and save that code to a variable. I'll play with it.
I guess I need to play with the <xsl:key/>'s some more. The code does not seem obvious to me at all....

I hope this helps.
