Subject: Re: [xsl] grouping references so that they only appear once From: "G. Ken Holman" <gkholman@xxxxxxxxxxxxxxxxxxxx> Date: Thu, 29 May 2003 07:40:27 -0400 |
I have a grouping problem that I am hoping someone can help me with. Imagine that I am transforming the following instance, and that I am currently processing the category element with the id "shoes". ... <makers> <maker id="nike">Nike</maker> <maker id="rebok">Rebok</maker> </makers> ... <products> <product> ... <makerRef idref="nike"/> </product> <product> ... <makerRef idref="nike"/> </product> <product> ... <makerRef idref="rebok"/> ... I want to get a list of all the makers that have products that reference the shoes category, but I don't want a single maker to appear more than once. I have been able to use keys to gather a list of products that reference a category, and from there I can get the makerRefs, and with another set of keys I can then get the makers, but I can't see how to ensure that each maker is only listed once since multiple products reference the same makers.
