Subject: [xsl] Muenchian Grouping with Position() Constraints From: "McDonald, Thomas" <Thomas.McDonald@xxxxxxxxxxxxxx> Date: Fri, 13 Jun 2003 09:56:19 -0400 |
Hi, I am doing some Muenching grouping and in the result I want to constrain the output, i.e., I don't want to show anything that matches the first three key values. For example, imagine you were making a phone book from the following xml and you wanted to not show the first three names in the key (I assume the key is kept in document order so I want to eliminate all names that are Aarron, Aiken or Appleby). <names> <name><lname>Aarron</lname><first>Hank</first><name> <name><lname>Aarron</lname><first>Ted</first><lname> <name><lname>Aiken</lname><first>Joe</first></name> <name><lname>Aiken</lname><first>Jill</first></name> <name><lname>Appleby</lname><first>Joe</first></name> <name><lname>Appleby</lname><first>Sarah</first></name> <name><lname>Appleseed</lname><first>John</first></name> <name><lname>Appleseed</lname><first>Susan</first></name> <name><lname>Arson</lname><first>Joe</first></name> <name><lname>Arson<lname><first>Bill</first></name> <name><lname>Azzure<lname><first>Peg</first></name> </names> Consequently the result tree should look like <names> <name> <lname>Appleseed</lname> <first> <fname>John</fname> <fname>Susan</fname> </first> </name> <name> <lname>Arson</lname> <first> <fname>Joe</fname> <fname>Bill</fname> </first> </name> <name> <lname>Azzure</lname> <first> <fname>Peg</fname> </first> </name> </names> Notice that the top three names from the document didn't appear in the result tree. Regards, Tom fyi, if you want to know why I would do such a thing, just imagine that I am selling phone books and people who pay get the WHOLE phone book, including the first three names of every letter. People who don't pay get the PARTIAL phone book (excluding the first three people from every letter) until they pay. Muuuhuuuuhahahahahahahah! Also, I must constrain by position in the document so please don't offer a suggestion based on alphabetizing or some other system. XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
