Subject: [xsl] problem with keys and Meunchian method From: mark_fletcher@xxxxxxxxxxxxxx Date: Wed, 17 Nov 2004 12:10:10 -0800 |
Hi all, I'm having a problem pulling distinct nodes out of some xml with duplicate values at multiple levels. In all cases, I want to get the data from the last node of a set that shares duplicate values. (This xml will be in a file that gets appended to multiple times. So I can assume that the last tags are the most current.) In the xml below, what I'm trying to do is get a list of distinct book/code values from the last prodline where name=PL1. I can successfully get the prodline using this select statement: <xsl:for-each select="prodline[code='PL1'][last()]"> But I'm having no luck getting a list of distinct book/code values from this particular prodline. I've tried creating keys and using the Meunchian method of comparing generate-id() values, but to no avail. Any help would be greatly appreciated! Here's the xml: <prodlines> <prodline> <name>Product Line 1</name> <code>PL1</code> <product> <name>Product 1</name> <code>P1</code> <book> <name>Book 1</name> <code>B1</code> </book> <book> <name>Book 2</name> <code>B2</code> </book> </product> <product> <name>Product 2</name> <code>P2</code> <book> <name>Book 1</name> <code>B1</code> </book> <book> <name>Book 3</name> <code>B3</code> </book> <book> <name>Book 4</name> <code>B4</code> </book> </product> </prodline> <prodline> <name>Product Line 2</name> <code>PL2</code> <product> <name>Product 1</name> <code>P1</code> <book> <name>Book 1</name> <code>B1</code> </book> </product> </prodline> <prodline> <name>Product Line 1 (ver 2)</name> <code>PL1</code> <product> <name>Product 1</name> <code>P1</code> <book> <name>Book 1</name> <code>B1</code> </book> <book> <name>Book 2</name> <code>B2</code> </book> <book> <name>Book 5</name> <code>B5</code> </book> </product> <product> <name>Product 2</name> <code>P2</code> <book> <name>Book 1</name> <code>B1</code> </book> <book> <name>Book 2</name> <code>B2</code> </book> <book> <name>Book 3</name> <code>B3</code> </book> <book> <name>Book 4</name> <code>B4</code> </book> </product> </prodline> </prodlines> Mark Fletcher PeopleSoft Language Engineering 925.694.3753 mark_fletcher@xxxxxxxxxxxxxx
