RE: [xsl] Counting items related by a linked list

Um, given rule #4 isn't the maximum count going to be 1? Or is that the point... Are you trying to enforce this rule by checking the count? Or am I just missing the boat completely here? I tried going with the idea that a CItem could be linked to more than once but after looking at your sample data I'm not even sure if rule #3 can be considered true. I guess I'm just a bit confused... can you clarify your problem a bit more? Thanks! <M:D/> -----Original Message----- From: Joe K [mailto:anotherquestion@xxxxxxxxxxx] Sent: Monday, March 22, 2004 10:17 PM To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Cc: anotherquestion@xxxxxxxxxxx Subject: [xsl] Counting items related by a linked list I have the following type of xml document: Note: 1) All IDs are unique and can be any positive number 2) The link pairs below can link any item to any different Item. 3) CItems are always in the "Target" portion of the link table. 4) No item can be linked more than once to another item. The question: I would like to define a variable such that given the CItem ID, say 1003, I can get a count of all the AItems linked to it. <TopLevel> <AItem> <ID=1/> <Name=./> </AItem> <AItem> <ID=2/> <Name=./> </AItem> <AItem> <ID=3/> <Name=./> </AItem> <AItem> <ID=4/> <Name=./> </AItem> <AItem> <ID=5/> <Name=./> </AItem> <BItem> <ID=101/> <Name=./> </BItem> <BItem> <ID=102/> <Name=./> </BItem> <BItem> <ID=103/> <Name=./> </BItem> <BItem> <ID=104/> <Name=./> </BItem> <BItem> <ID=105/> <Name=./> </BItem> <BItem> <ID=106/> <Name=./> </BItem> <CItem> <ID=1001/> <Name=./> </CItem> <CItem> <ID=1002/> <Name=./> </CItem> <CItem> <ID=1003/> <Name=./> </CItem> <CItem> <ID=1004/> <Name=./> </CItem> <CItem> <ID=1005/> <Name=./> </CItem> <CItem> <ID=1006/> <Name=./> </CItem> <CItem> <ID=1007/> <Name=./> </CItem> <LinkItem> <SourceID>4</SourceID> <TargetID>1003</TargetID> </LinkItem> <LinkItem> <SourceID>6</SourceID> <TargetID>1003</TargetID> </LinkItem> <LinkItem> <SourceID>105</SourceID> <TargetID>1002</TargetID> </LinkItem> <LinkItem> <SourceID>3</SourceID> <TargetID>101</TargetID> </LinkItem> <LinkItem> <SourceID>4</SourceID> <TargetID>1003</TargetID> </LinkItem> <LinkItem> <SourceID>102</SourceID> <TargetID>1</TargetID> </LinkItem> <LinkItem> <SourceID>101</SourceID> <TargetID>1003</TargetID> </LinkItem> </TopLevel> _________________________________________________________________ Get rid of annoying pop-up ads with the new MSN Toolbar - FREE! http://clk.atdmt.com/AVE/go/onm00200414ave/direct/01/
