Maybe someone can answer this. I copied the code and tried to test it in
Cocoon2. Unfortunately, I am getting lots of error in it. For example,
Cocoon2 does not like "select='.'", nor does it like the <xsl:sort>
statement on line 25. 

Here is my cocoon sitemap entry:
   <map:match pattern="test.html">
    <map:generate src="testing/test.xml"/>
    <map:transform src="testing/test.xsl"/>
    <map:serialize type="html"/>
   </map:match>   
   

I have every confidence that I should get some output, at least to what
Anand gets. Why the discripency?

Hi All,
I need some help in the following:

I'm trying to create 2 drop-down boxes, one selecting distinct month, and
the other selecting distinct days for a given month from the previous
drop-down box. Hope it is clear so far.

My XML file looks like:
<page>
   <Audits>
      <Audit AuditID="694" Year="2001">
         <Day>15</Day>
         <Month>JUL</Month>
         <SourceFile>15Jul2001.01Aug20011650</SourceFile>
      </Audit>
      <Audit AuditID="705" Year="2001">
         <Day>18</Day>
         <Month>AUG</Month>
         <SourceFile>18Aug2001.02Aug20011921</SourceFile>
      </Audit>
      <Audit AuditID="739" Year="2001">
         <Day>18</Day>
         <Month>JUL</Month>
         <SourceFile>18Jul2001.04Aug20011612</SourceFile>
      </Audit>
   </Audits>
</page>


My desired output should be:
Month Dropdown = JUL (selected), AUG
Days Dropdown for 'JUL' = 15, 18

Below is my version of XSL file. I'm able to create a drop-down for distinct
months. But, am not able to get the distinct days for the first month, in
this case 'JUL'. Something is not correct with the way I'm passing
parameters.

<?xml version="1.0"?>

   <xsl:param name="monthname" />

   <xsl:template match="/">
      <FORM NAME="blank_form">
         <xsl:apply-templates select="page/Audits"/>
      </FORM>
   </xsl:template>

   <xsl:template match="page/Audits">

      <SELECT>
         <xsl:attribute name="name">
            <xsl:value-of select="'cycleMonth'"/>
         </xsl:attribute>

         <OPTION VALUE="cycleMonth">--MONTH--</OPTION>
         <xsl:for-each
select="Audit/Month[generate-id(.)=generate-id(key('mon-index',.)[1]/Month)]
">
            <OPTION>
               <xsl:sort select="."/>
               <xsl:with-param name="monthname" >
                  <xsl:value-of select="."/>
               </xsl:with-param>
               <xsl:attribute name="value">
                  <xsl:value-of select="."/>
               </xsl:attribute>
               <xsl:value-of select="."/>
            </OPTION>
         </xsl:for-each>
      </SELECT>

      <SELECT>
         <xsl:attribute name="name">

         </xsl:attribute>

         <xsl:param name="monthname"/>
         <xsl:for-each select="key('mon-index',$monthname)">
            <OPTION>
               <xsl:sort select="Month"/>
               <xsl:attribute name="value">
                  <xsl:value-of select="Day"/>
               </xsl:attribute>
               <xsl:value-of select="Day"/>
            </OPTION>
         </xsl:for-each>
      </SELECT>

   </xsl:template>

</xsl:stylesheet>
