Subject: [xsl] 'Variable' question from Newbie From: "Surla, Stacy" <SSurla@xxxxxxxxxxxx> Date: Fri, 8 Nov 2002 16:17:04 -0500 |
I (superficially) understand that you can't change the value of a variable once it's defined. But although I've looked through the list FAQs and other sources, I haven't yet grasped how one goes about doing certain things that would be possible, if only one could update a variable each time through a loop. Here's my problem. I have a collection of publications records in XML that store Discipline, Title, Date, and other characteristics, including a flag indicating whether the publication should show up on a Highlights page. I now want to output the Highlights page, and I want the value of Discipline to be output only once per group of records sharing that discipline. E.g. JAILS Title of Report1, publisher1, date1 Title of Report2, publisher2, date2 [link to Jails subpage] PRISONS Title of Report3, publisher3, date3 Title of Report4, publisher4, date4 [link to Prisons subpage] In the olden days I would have used something like the following logic: Sort by Discipline For each record, Check if Highlights = True If yes, Check if Discipline = $var If no, Put the value of Disciplines into $var Output the value of $var Output values of Title, Publisher, and Date If yes, Output values of Title, Publisher, and Date I can't do it like this in XSLT. In fact, I have to learn not to THINK like this, I'm starting to realize. Can someone please explain to me how I would accomplish the same end? Thanks very much in advance for any help. Below is a sample of my XML. ~Stacy <InstCorr> <Record> <Title>BJS Drugs & Crime Facts</Title> <Disciplines>Institutional Corrections, Jails</Disciplines> <Highlights_Discipline>1</Highlights_Discipline> </Record> <Record> <Title>Drug Treatment in the Criminal Justice System</Title> <PubDate>March 2001</PubDate> <Disciplines>Institutional Corrections, Jails</Disciplines> <Highlights_Discipline>0</Highlights_Discipline> </Record> <Record> <Title>Assessing Alcohol, Drug, and Mental Disorders in Juvenile Detainees</Title> <PubDate>January 2001</PubDate> <Disciplines>Institutional Corrections, Jails</Disciplines> <Highlights_Discipline>1</Highlights_Discipline> </Record> <Record> <Title>TRIAD Drug Treatment Evaluation Project</Title> <PubDate>September 2000</PubDate> <Disciplines>Institutional Corrections, Prisons</Disciplines> <Highlights_Discipline>0</Highlights_Discipline> </Record> <Record> <Title>Institute for Criminal Justice Healthcare</Title> <Disciplines>Institutional Corrections, Prisons</Disciplines> <Highlights_Discipline>1</Highlights_Discipline> </Record> <Record> <Title>Therapeutic Communities in Correctional Settings</Title> <PubDate>November 1999</PubDate> <Disciplines>Institutional Corrections, Prisons</Disciplines> <Highlights_Discipline>1</Highlights_Discipline> </Record> <Record> <Title>Substance Abuse Treatment Programs in the Federal Bureau of Prisonss</Title> <PubDate>January 1999</PubDate> <Disciplines>Institutional Corrections, Prisons</Disciplines> <Highlights_Discipline>0</Highlights_Discipline> </Record> </InstCorr> XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
