Conditional inclusion

[Brian Charlton <brian dot charlton at vega dot co dot uk>]

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} &gt;
{Results/LastIndex/row/LASTINDEX}" >

does not compute.

Any good samaritans out there?
