Re: counting specific nodes

James,

the cheapest way to do this would be to count the length of each '@pos'.  If 
you can guarantee that there is only a single digit between each dot then a 
simple statement such as:

<xsl:variable name="rowspan" select="count(//ve/@pos[string-length(.) = 
7])"/>

would do the trick.  Another option would be:

<xsl:variable name="rowspan" 
select="count(//ve/@pos[string-length(substring-after(.,'.')) &gt;= 4])"/>

but if you are going to add additional function calls you might as well just 
do the following:

<xsl:variable name="rowspan" 
select="count(//ve/@pos[string-length(translate(.,'0123456789','')) = 3])"/>

the above strips out all the numbers leaving only the dots.  then a simple 
string-length test will tell you how many dots are left.

NOTE: changing your context node will allow you to decide which node to 
start your test with.

Best regards,

M.
