If you were to have your file divided into numbered units (1, 1.1, 1.2, 1.2.1, 1.2.2, etc.) you could grab the number attribute of the ancestor parent of each individual instance of <index>. The reference to a numbered chunk of text is not uncommon, and easy enough to navigate (as long as your text chunks are of a medium size), and would allow you to repurpose the same data for eBooks, etc., where pagination varies according to user settings. -----Original Message----- From: Gustaf Liljegren [mailto:gustaf.liljegren@xxxxxx] Sent: 25 September 2001 11:09 To: XSL List Subject: [xsl] Generating indexes 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 XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
