I was wondering if I can check if the string-length for a element is greater
than 0 and then display the required results.
Is there any method like that?
The easiest way is simply test="$string". A string tests as true if it has
content, false if it is empty (has length zero).
There is also a string-length function, but test="string-length($string)
> 0" is a long way of testing the same thing as test="$string".
When operating on an element (or rather, on a node set containing a single
node), test="string($element)" will do it. The string() function turns its
operand into a string; a node set turned into a string is the string value
of the first node in the set in document order. So if the element you want
to test is the current node, of course this can be test="string(.)" or even
"string()", since the default operand is the context node of the function.
On the Mulberry web site is a Quick Reference page to XSLT/XPath 1.0 which
lists all the standard functions. See
