Hi,
I am trying to calculate the string length of all @label attributes in
any element.
When I apply string-length(//@label) in the root I only get the length
of the first attribute. But count(//@label) works fine.
Because string-length expects a string argument and count a node-set. See the
casting rules <http://www.w3.org/TR/xpath#function-string>.
You need to write a recursive template that goes throught the nodes in the
node-set and sums the string-lengths, or if you're using XPath 2.0, then
something in the lines of sum(for $i in //@label return string-length($i)).
