Hopefully a very quick question: I have an attribute such as @class, which may have a value "h1", "H2" etc. I want to calculate how many distinct values are there so that "H2" and "h2" are counted as two occurrences, but following occurrences of either do not increment a counter. Basically a quality metric for a consistency of a document. > > yep If the attribute is @class, and the intent is to run this on data in the wild, keep in mind also that any html:*/@class may also have several (space-delimited) values. So count(distinct-values(//@class/tokenize(.,'\s+'))) Cheers, Wendell -- ====================================================================== Wendell Piez mailto:wapiez@xxxxxxxxxxxxxxxx Mulberry Technologies, Inc. http://www.mulberrytech.com 17 West Jefferson Street Direct Phone: 301/315-9635 Suite 207 Phone: 301/315-9631 Rockville, MD 20850 Fax: 301/315-8285 ---------------------------------------------------------------------- Mulberry Technologies: A Consultancy Specializing in SGML and XML ======================================================================
