You will find the solution to this example on p19 of my book, XSLT 2.0
and XPath 2.0 Programmer's Reference. In case you don't have the book,
here is the code (but if you do have the book, you get an explanation as
well!)
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet
version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<wordcount>
<xsl:for-each-group group-by="." select="
for $w in //text()/tokenize(., '\W+')[.!=''] return
lower-case($w)">
<xsl:sort select="count(current-group())" order="descending"/>
<word word="{current-grouping-key()}" frequency="{count(current-group())}"/>
</xsl:for-each-group>
</wordcount>
</xsl:template>
</xsl:stylesheet>
This is sorted by frequency - I leave it as an exercise to sort by the
word value instead.

Hi,
I have been floundering around in the xsl-list archives for a while
looking for a way to get a listing and count of all the words in every
instance of a specific element. Thousands of hits, but I think I am
not using the correct search terms. I know what I want must be in the
archive, but I just can't seem to narrow my search enough to find it.
Given a fragment like (and concentrating on the moment on the
lang="en" element):
<Description>
<Data lang="cz"> bmla skvrnka na spodnm casti pmsmene L ve SLOV</Data>
<Data lang="en">white splotch on the lower bar on the L in SLOV</Data>
</Description>
<Description>
<Data lang="cz">barevn} bod pod dolnmm ramem vlevo od VHB</Data>
<Data lang="en">dot on the lower frame to the left of VHB</Data>
</Description>
I would like to create a list like the one below (it would be nice to
be able to use a "stop word" list also so as to not count stuff like
"on", ""the", etc.):
bar 1
dot 1
frame 1
in 1
L 1
left 1
lower 2
of 1
on 3
SLOV 1
splotch 1
the 3
to 1
white 1
