Subject: Indexing Tree Elements (repost) From: Lee Goddard <home@xxxxxxxxxxxxxx> Date: Thu, 17 Aug 2000 11:56:11 +0100 |
Hi Folks, I've been using a line suggested below by Ken Holman <xsl:if test="not(@foo = preceding-sibling::*[@foo][1]/@foo)"> to only reveal certain content if it is there is a difference between attribute values found in the node immediately preceeding the current node. It seemed to work for a while, but now seems to show the value of the first node's attribute. I've got around this by using the same code but replacing 'preceding' with 'following'. But has anyone any idea what the problem might be? Thanks in anticipation, lee goddard -- Lee Goddard <l.goddard@sussex> Research Centre for Cognitive Science, University of Sussex, Brighton UK "G.
