xml sorting and counting

[Rohit Bhalerao <ro...@hotmail.com>]

hi there!
I want to count the number of elements in my xml..
I am using the xml file like this..

<?xml version="1.0"?>
<?cocoon-process type="xslt"?>
<?xml-stylesheet href="testcount.xsl" type="text/xsl" ?>

<root>
	<foo>
         <bar>bard</bar>
           <bar>bark</bar>
     </foo>
     <foo>
           <bar>bark</bar>
           <bar>barb</bar>
      </foo>
</root>

and the xsl is

<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:template match="/">
    <xsl:for-each select="//bar">
      <xsl:variable name="value" select="."/>
      <xsl:if test="count(preceding::bar[.=$value]) = 0">


<xsl:value-of select="."/><xsl:text> : </xsl:text>


	<xsl:value-of select="count(//bar[.=$value])"/>
	<xsl:text>&#xA;</xsl:text>
      </xsl:if>
    </xsl:for-each>
  </xsl:template>

</xsl:stylesheet>


its giving me exception like
                                               
org.apache.xalan.xslt.XSLProcessorException: Warning: can't output text 
before document element!  Ignoring...

please correct me.

Rohit
