Subject: [xsl] Generating indexes From: "Gustaf Liljegren" <gustaf.liljegren@xxxxxx> Date: Tue, 25 Sep 2001 12:08:44 +0200 |
I have a document in XML with some words marked up with <index> tags. This document is later going to be transformed into PDF and printed like a book, with an index. I'm aiming to do this task automatically. The general idea is to collect the words and phrases marked-up with <index>, plus the pages on which they appear, to get a list of all matches, in no particular order, or possibly document order. In a positional flat file, it may look like this: 12 yoghurt 153 milk 122 yoghurt 132 egg 43 olive oil 32 egg As soon as I have the page numbers I have total control when producing an index. I can do scripts that handle cases like 121, 123, 124, 125 (should be "121, 123-125"). I can handle special characters like á, é, å, ä and ö so they appear in correct order and so on. The hard thing is to generate this file of matches. Of course, XSLT can't know anything about page-numbers, so I guess this is something that has do be drawn from a rendering engine. Before digging deeper into this, I wonder if anyone has achieved it, or been successful in alternative ways. Just to clarify: I'm not aming at doing a full-blown index. This should be a one-level index, and the indexing work (placing <index> tags around certain words in certains elements) is still a work for a human indexer, or to intelligent scripts. In fact, I made an indexing script, but it's not intelligent enough to know about mouse and mice... :-) Gustaf XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
