Question

Hello Guru's,
I am new to XSL templates, while genrating XML publisher report with these template, I am getting below "namespace" error:
If I remove the "set:"/"str:" expressions from the template, it works fine. Is there anything syntactically wrong in the expression? but not getting the results
Getting "Caused by: oracle.xdo.parser.v2.XMLParseException: Namespace prefix 'str' used but not declared." error while using this code
                         <xsl:call-template name="str:generate-string">
                              <xsl:with-param name="text" select="' '"/>
                              <xsl:with-param name="count" select="30"/>
                         </xsl:call-template>
Getting "Caused by: oracle.xdo.parser.v2.XMLParseException: Namespace prefix 'set' used but not declared." error while using this code

          <xsl:param name="nodes" select="/.."/>
          <xsl:param name="distinct" select="/.."/>
          <xsl:choose>
               <xsl:when test="$nodes">
                    <xsl:call-template name="distinct">
                         <xsl:with-param name="distinct" select="$distinct | $nodes[1][not(. = $distinct)]"/>
                         <xsl:with-param name="nodes" select="$nodes[position() &gt; 1]"/>
                    </xsl:call-template>
               </xsl:when>
               <xsl:otherwise>
                    <xsl:apply-templates select="$distinct" mode="set:distinct"/>
               </xsl:otherwise>
          </xsl:choose>
     </xsl:template>
I would appreciate any help in this regard.

Declare them in the namespace :)
<?xml version='1.0' encoding='windows-1252'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template name="distinct">
<xsl:param name="nodes" select="/.."/>
, </xsl:stylesheet>
