John,

There's a trick for this too (let's see if I can get it right this time):

<xsl:variable name="commacount"
   select="string-length(@cols) - (string-length(translate(@cols, ',',''))"/>

Basically you're subtracting the string length of the string stripped of commas from the string length of the string with the commas in it.

In your case, add 1.

And yes, you could do it with recursion too.

Cheers,
Wendell

another newbie question. Is there an easy way to count
the number of commas in a string? Like this:

<ITEM cols="col1,col2,col3,col4"/>

I would like to print 4 for the number of columns in
my ITEM. I searched on tokenize() but most of the
references are about the existence of it.
