Subject: [xsl] what index is the current item in a list? From: "Lee Breisacher" <LBreisacher@xxxxxxxxxxxxxxxxxxx> Date: Tue, 2 Aug 2005 15:19:31 -0400 |
I want to do something that seems like it should be easy, but I cannot figure it out. I have a list of items like this in the input XML: <Item> <Type>type1</Type> .. Other elements here.. </Item> <Item> <Type>type2</Type> .. Other elements here.. </Item> <Item> <Type>type1</Type> .. Other elements here.. </Item> <Item> <Type>type3</Type> .. Other elements here.. </Item> <Item> <Type>type2</Type> .. Other elements here.. </Item> Each "Type" is handled differently, so the templates look like this: <xsl:template match="*[Type = 'type1']"> .. Do type1 stuff here.. </xsl:template> <xsl:template match="*[Type = 'type2']"> .. Do type2 stuff here.. </xsl:template> <xsl:template match="*[Type = 'type3']"> .. Do type3 stuff here.. </xsl:template> Now, further down in the input XML is another list of items related to, say, type2 Items, in the same order as in the Item list, like this: <Type2Info> .. Elements related to the first type2 item is here.. </Type2Info> <Type2Info> .. Elements related to the second type2 item is here.. </Type2Info> So, I'm inside the second match template above and I want to get at the proper Type2Info element. Logically, what I want to do is this: "Get the Nth Type2Info node where N is the ordinal number of the type2 Item within the list of type2 Items." I can make a list of just the type2 Items, that's easy. And I can access the Nth Type2Info item, that's easy. I can even find the current type2 Item within the list of type2 Items, but I can't see how to determine what N is. I've studied position() and xml:number and count(), etc. but nothing seems quite what I need. Help! Thanks, Lee
