I've done something like this to count words (courtesy of somebody from this
list):
<xsl:variable name="sql"><xsl:value-of select="RowSource"
/></xsl:variable>
<xsl:variable name="x" select="normalize-space($sql)" />
<xsl:variable name="y" select="translate($sql, ' ', '')" />
<xsl:variable name="wc" select="string-length($x) -
string-length($y) +1" />
wc = word count.

Try this

You could store every template defined above except the first one in a file
called utils.xsl and use it.
Hope this helps

Subject: [xsl] Count Words
Date: Sun, 8 Aug 2004 13:18:41 -0700
Hello,
Given the following:
=========== xml source ==========
<poem>
<hey_diddle>
Hey diddle diddle, the cat and the fiddle,
The cow jumped over the moon,
The little dog laughed to see such sport,
And the dish ran away with the spoon.
</hey_diddle>
</poem>
=========== /xml source ==========
How do I count how many words are contained within the node <hey_diddle/>?
Karl
