[xsl] The longest node in a node set

[Antonio Fiol Bonnín <fiol at w3ping dot com>]

Hello,

I am trying to find an XPath expression that gives me the longest 
element in a node set.

I know how to do that for an attribute. e.g //element[not(@attr < 
following-sibling::element/@attr)]

But how can I do that for the string-length(element).

I tried //element[not(string-length(.) < 
string-length(following-sibling::element))]

But this obviously does not work, because following-sibling::element is 
not an element or string, but a node-set.

Any ideas?

(I think this one is for Michael Kay... Am I wrong?)

Thank you very much.
