if test syntax

  Hi

  I want to compare a variable in query string with
value of XML tag using if-text of xsl but I can not
find out the correct syntax for it.

  Here's example of xml file:
<q>
  <o>
   <n>1</n>
   <v>first value</v>
  </o>
  <o>
   <n>2</n>
   <v>second value</v>
  </o>
</q>

  The http request is: "test.html?o=1". 
  Then the concerning part of xsl file:
<xsl:for-each select="q/o">
  <xsl:if test='?????'> <!--compare 2 values-->
    <script type="text/javascript">
      document.write('<xsl:value-of select="e/r"/>');
    </script>
  </xsl:if>
</xsl:for-each>

  I tried many different code to put into "if test"
but it doesnt work. 

  Does anyone know what I should do, please? (I want
to use if-test of xsl for the comparation)

  Thanks a lot

Dinh Tran
