 Fundimentle Predicate Problem or Bug??
Hi

I tried asking for help a while back on this, anyway now I have worked out
exactly where my issue is and will provide examples below.

Assume this data....

<?xml version="1.0" encoding="utf-8"?>
<ORCB082>
   <ROWSET>
      <ROW num="1">
        <Fixture>
            <FixtureDate>2008-10-17</FixtureDate>
            <FixtureDayText>DAY ONE TEST</FixtureDayText>
            <Race>
               <RaceType>S</RaceType>
            </Race>
            <Race>
               <RaceType>H</RaceType>
            </Race>
         </Fixture>
      </ROW>
   </ROWSET>
</ORCB082>


Stylesheet 1
------------

This stylesheet outputs "DAY ONE TEST" message, IMO it should match no records
and not output anything.

<?xml version="1.0"?>
  <xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                                xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xsl:output method="text" indent="yes"/>

  <xsl:template match="/">

  <xsl:for-each select="/ORCB082/ROWSET/ROW/Fixture[FixtureDate &gt;=
'2008-01-01' and FixtureDate &lt;= '2010-01-01' and
                                                    Race/RaceType &gt;= 'R'
and Race/RaceType &lt;= 'R']" >

    <xsl:message><xsl:value-of select="FixtureDayText"/></xsl:message>
  </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>


Stylesheet 2
------------

This stylesheet outputs nothing - which is what I would expect, but
essentially is stylesheet 1 not performing the same logic as 2?


<?xml version="1.0"?>
  <xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                                xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xsl:output method="text" indent="yes"/>

  <xsl:template match="/">

  <xsl:for-each select="/ORCB082/ROWSET/ROW/Fixture[FixtureDate &gt;=
'2008-01-01' and FixtureDate &lt;= '2010-01-01' and
                                                    Race/RaceType = 'R']" >

    <xsl:message><xsl:value-of select="FixtureDayText"/></xsl:message>
  </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>

Conclusion
-----------

Like so many of us working in the XML / XSLT world I find it difficult to
adjust to a different way of working.  Essentially had I wrote this logic in
SQL or 4GL or VB etc etc I'd be sure that it would work.  I hope nobody is
offended by me suggesting this may be a bug!

Thanks in advance.
