[xsl] Complicated next for-each and need to display page not found if no data

[Chris Hughes <chris_hughes22@xxxxxxxxxxx>]

Hi all

Im trying to write a solution where if no data is found I write out a message
saying so and if data is found I continue to process on the assumption that
the innermost nested for-each will find some data.

The problem is that my check says there is data, but my inner most for each on
"Race" finds no data.  Therefore I end up with header info and no detail....

The following is snippets of my code..

  <xsl:variable name="getdata" select="/ORCB082/ROWSET/ROW
    [Fixture/Race/RaceType &gt;= $racetypefrom]
    [Fixture/Race/RaceType &lt;= $racetypeto]
    [Fixture/Race/RaceAgeFrom &gt;= $agefrom]
    [Fixture/Race/RaceAgeTo &lt;= $ageto]
    [Fixture/Race/RaceDistance &gt;= $racedistancefrom]
    [Fixture/Race/RaceDistance &lt;= $racedistanceto]
    [Fixture/FixtureDate &gt;= $datefrom]
    [Fixture/FixtureDate &lt;= $dateto]" />

<!-- If no data has been found -->
  <xsl:if test="not($getdata)">
NOTHING FOUnd!!
  </xsl:if>

<!-- If data is found -->
  <xsl:if test="($getdata)">
I OUTPUT OVERALL HEADER
    <xsl:for-each select="$getdata">
I OUTPUT ROW HEADER
      <xsl:for-each select="Fixture[FixtureDate &gt;= $datefrom]
                                   [FixtureDate &lt;= $dateto]">
I OUTPUT FIXTURE HEADER
        <xsl:variable name="racedata">
          <xsl:for-each select="Race[RaceType &gt;= $racetypefrom]
                                    [RaceType &lt;= $racetypeto]
                                    [RaceAgeFrom &gt;= $agefrom]
                                    [RaceAgeTo &lt;= $ageto]
                                    [RaceDistance &gt;= $racedistancefrom]
                                    [RaceDistance &lt;= $racedistanceto]">
            <xsl:sort select="RaceCloseDate"/>
            <xsl:copy-of select="."/>
          </xsl:for-each>
        </xsl:variable>


        <xsl:for-each select="$racedata/*">
I WANT TO OUTPUT RACE DATA BUT I DON'T GET HERE????
.

This is an overview of my code  - I built this using ideas pinched from
various forums i.e. put the for-each into a variable then do an if for the no
data found.  None of the examples I saw used nested for-each's though.

I'm sure I'm missing something simple somewhere but its late so any help from
the usual suspects would be much appreciated.

Thanks in advance.
