If you want to constrain the XPath expression's application to the preceding siblings of "member", then use the preceeding-sibling axis. -- Charles Knell cknell@xxxxxxxxxx - email -----Original Message----- From: Charlie Consumer <faceless1976@xxxxxxxxx> Sent: Tue, 5 Oct 2004 07:27:34 -0700 (PDT) To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: [xsl] Help culling out duplicates with preceding:: Hi, I'm trying to cull out duplicate XML by using preceding:: axes as discussed in the FAQ. I'm having trouble doing so. My XSL takes in an ID as a parameter. Then it selects out all the sibiling nodes that the ID is in. For example: <mesh name='A'> <member id='1'/> <member id='2'/> <member id='3'/> </mesh> <mesh name='B'> <member id='4'/> <member id='5'/> <member id='6'/> <member id='1'/> <member id='2'/> </mesh> My XPATH query is something like the following: mesh/member[not(@id=$thisId) and not(@removed) and not( @id = preceding::member[not(@removed)]/@id )] In the case where thisId='1' it would select the following: from mesh A members with 2 and 3 and from mesh B 4, 5, and 6 which is what I expect. But in the case where thisId='4' it would select only 4, 5, and 6. I was expecting it would select from mesh B 1 and 2, but the preceding:: axes culled it out. I understand why it did because the preceding:: axes isn't constrained to just the nodes that are 4's siblings. But, I'm not sure how to make it contrained to 4's siblings. Can someone help me with what I'm missing? What the query is trying to accomplish is where ever thisId is a member of a mesh. I want to select out all the siblings of that mesh. If he belongs to more than one mesh any duplicates between the meshes (i.e. when thisId='1' 2 is a dup). Only give me the first occurence of that dup.
