Re: intersection of different node types
Is it meaningful to take the intersection of a sequence of element nodes and a sequence attribute nodes, like this: It's meaningful but doesn't mean what you want it to mean (it will always be the empty sequence). intersect (like union) works on node identity. so two nodes are distinct even if they have the same string value. <xsl:variable name="intersection" select="a/b/text() intersect c/@d/text()"/> attribute nodes don't have children so @d/text() is the empty sequence. intersecting any sequence with teh empty sequence will result in the empty sequence. To compare string (typed) values rather than node identity just use the same expression as in xpath1 you want all a/b that are not equal to a value of a node in c/@d so that is a/b[not(. = current()/c/@d)] David ________________________________________________________________________ This e-mail has been scanned for all viruses by Star.
