RE: [xsl] How do I get a SUM of the string-length of all child nodes ??

["Michael Kay" <mike@xxxxxxxxxxxx>]

In XSLT 1.0 the sum() function can only sum the string values of nodes, it
can't sum a set of computed numbers. This means your options are

(a) a two-phase transformation: first create a tree in which the computed
numbers are represented as attributes (typically), then sum over these
attributes

(b) a recursive template to compute the sum

In 2.0, like many things, it's much easier:

    sum(child::node()/string-length())
