Re: Count a substring of an attribute in childnodes

sum() takes a set of nodes, each of which has to have a numeric value,
then sums them, returning the total:


  I tried 
  select="sum(number(

There the argument to sum() isn't a set of anything, it's a single
number (as returned by number() ) so you get an error and processing
stops, but even if that didn't error the only possible interpretation
for a sum of one number would be to return that number unchanged, so you
still wouldn't get a total.

> So it will be the recursive  template.

if you allow yourself an xx:node-set extension then the alternative
would be to do one pass that removes the"*" then you could just use
select="sum(colspec/@colwidth)
to get the total.
