Re: intersection puzzle
Your node sets are all taken from the same document and you do need (or at least can use) node identity so probably I'd use something like <xsl:key name="x" match="square" use="concat(@h,':',@v)"/> <xsl:variable name = "intersection" select = "$polo/square[count($marco/square)=count($marco/square|key(concat(@h+1,':',@v)))]"/> David ________________________________________________________________________ This e-mail has been scanned for all viruses by Star.
