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.
Actually, the replace() function is allowed in the group-by=
attribute and you can use regular expressions in that function.
I hope this helps.
