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(.,'.')) >= 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.
