> //row[preceding-sibling::row/attribute::UserName != > attribute::UserName]/attribute::UserName > XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list As a general rule, don't use X!=Y to compare node-sets, use not(X=Y). x!=y means "if there exists an x in X and a y in Y such that x!=y", in other words you are testing whether the username is different from every previous username, not whether it is different from some previous username.
