Hello,
I am creating an index of paper titles using xsl:for-each-group to select and
group by the titles of the papers alphabetically using the first character of
the title.
Eg:
<xsl:for-each-group select="//section"
group-by="upper-case(substring(normalize-space(paperTitle),1,1))">
<xsl:sort select="current-grouping-key()"/>
. . .
Some of the paper titles start with double left hand quotes. Others start
with a numeral. In those cases I want the group-by to use the first alpha
character in the title string. I could do this if regular expressions were
allowed in the group-by attribute, but they're not.
Can anyone suggest how to make this work?
Thanks,
Craig
