David one comment more or less unrelated to your grouping problem. > <xsl:for-each select="//person you probably don't (hardly ever) want to use // as it is very expensive causing the system to search the entire document to arbitrary depth looking for person elements. You may know there areno person elements inside <state>, but the system doesn't. ________________________________________________________________________ This e-mail has been scanned for all viruses by Star Internet.
