[xsl] counting the number of tokens in a string?

[john liao <jliao2k@xxxxxxxxx>]

Hi,

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.

Thanks,

J.L.
