Thank you Mike and David,
Both stylesheets are performing extremely well. I ran them on the complete
xml version of Hamlet and the results are: 657 milliseconds and 781
milliseconds -- respectively David's and Mike's transformation. Even though
my computer was 3GHz 2GB RAM these results are fantastic.
I think, these XSLT 2.0 examples completely disspell the myth that XSLT is
not to be used for (efficient) text processing.
Cheers,
Dimitre Novatchev.

Sorry for the buggy code. Here is a working version:
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output indent="yes"/>
<xsl:template match="/">
<frequencies>
<xsl:for-each-group group-by="." select="
for $w in tokenize(string(.), '[\s.?!,]+')[.] return lower-case($w)">
<xsl:sort select="count(current-group())" order="descending"/>
<word><xsl:value-of select="current-grouping-key(), ' - ',
count(current-group())"/></word>
</xsl:for-each-group>
</frequencies>
</xsl:template>
</xsl:stylesheet>
(The predicate [.] elimitates the zero-length string)
Here's the start of the output for othello.xml:

Sorted by descending frequency:
<xsl:for-each-group select="
for $w in tokenize(string(foo), "[\s.?!]*") return
lower-case($w)">
<xsl:sort select="count(current-group())" order="descending"/>
<xsl:value-of select="current-grouping-key(), ' - ',
count(current-group())"/> </xsl:for-each>
Sorry, but cannot make this work.
First had to remove the nested quotes. Then to change the ending tag.
Now I get the message:
"Error at xsl:for-each-group on line 10 of file:/(Untitled):
Exactly one of the attributes group-by, group-adjacent,
group-starting-with, and group-ending-with must be specified"
Probably this is something trivial, but this is the first
time I'm trying an XSLT 2.0 grouping example.
