Thank you. In other words, if I understand right, current() in the select expression of a for-each gives the context node as it is outside the for-each. So in this case, [xsl:for-each] > select="items/item[not(preceding-sibling::* > [name=current()/name and > type = current()/type and > status = current()/status])]" current() does not give what we would want if we were trying to find all unique items. Right (Wendell)? I think that's why I was confused... Lars XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
