Subject: Conditional inclusion From: Brian Charlton <brian.charlton@xxxxxxxxxx> Date: Wed, 2 Aug 2000 10:14:13 +0100 |
I am trying to produce an XSLT file which will translate XML to HTML. I have a specific XSL problem: The XML looks like this:- <?xml version='1.0' ?> <!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml"> <Results> <NumMatches><row><NUMMATCHES>18</NUMMATCHES></row></NumMatches> <WindowSize><row><WINDOWSIZE>10</WINDOWSIZE></row></WindowSize> <FirstIndex><row><FIRSTINDEX>1</FIRSTINDEX></row></FirstIndex> <LastIndex><row><LASTINDEX>11</LASTINDEX></row></LastIndex> <EventRecords> <row><SEQ>1</SEQ><TIMESTAMP>14:34:25.0</TIMESTAMP><EVENTTYPE>LGUT</EVENTTYPE ><EVENTSOURCE>FRAUD</EVENTSOURCE></row> <row><SEQ>2</SEQ><TIMESTAMP>14:34:26.0</TIMESTAMP><EVENTTYPE>LGIN</EVENTTYPE ><EVENTSOURCE>FRAUD</EVENTSOURCE></row> ... --- contains WINDOWSIZE records --- ... <row><SEQ>10</SEQ><TIMESTAMP>14:34:26.0</TIMESTAMP><EVENTTYPE>LGIN</EVENTTYP E><EVENTSOURCE>FRAUD</EVENTSOURCE></row> </EventRecords> </Results> I need to produce a list of events containing WINDOWSIZE records. I need to conditionally append a NEXT hyperlink at the end of the list of WINDOWSIZE records if LASTINDEX < NUMMATCHES. I have a template which converts each <Results><EventRecords><row> element into HTML. How do I conditionally include the NEXT option? IN XSLT I need to somwhow encode:- if LASTINDEX < NUMMATCHES then include NEXT Anyone have any idea? I've considered creating a param/variable with the value of the NUMMATCHES element but all of the examples I have seen always assign a constant. I imagine that the order in which template are applied cannot be guaranteed. I have also tried xsl:if but I cannot figure out how to construct the test:- <xsl:if test="{Results/NumMatches/row/NUMMATCHES} > {Results/LastIndex/row/LASTINDEX}" > does not compute. Any good samaritans out there? Regards Bri XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
