Re: [xsl] is there a way to hash an element?

["Dimitre Novatchev dnovatchev@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

I would also try to use the standard XPath 2.0 function:

    deep-equal()

Yes, it doesn't generate an id for identifying a sub-tree, but still
can be used for establishing classes of equivalence.

Just a quick thought.

Cheers,
Dimitre

Quality means doing it right when no one is looking.

You've achieved success in your field when you don't know whether what
you're doing is work or play
-------------------------------------
To achieve the impossible dream, try going to sleep.

Typing monkeys will write all Shakespeare's works in 200yrs.Will they
