RE: [xsl] Help with Parameters

When you look at the source document, how can you tell which <desc> elements you want to process with the "leader" mode template and which you want to process with the modeless template?

Dear All:

I am trying to implement a parameter into my style sheet, but am having some problems.

I need to output the <desc> element in two different ways.

I first introduce the parameter with the following code:

<xsl:apply-templates select="parent::example/desc" mode="leader">
<xsl:with-param name="special_desc">yes</xsl:with-param>
</xsl:apply-templates> 

The template for <desc> is:

<xsl:template match="example/desc" mode="leader">
 <xsl:param name="special_desc"/>
<xsl:choose>
<xsl:when test="$special_desc='yes'">
<fo:wrapper font-style="italic" font-weight="normal">
   <xsl:text>    </xsl:text>
   <xsl:value-of select="."/>
  </fo:wrapper>
</xsl:when>
<xsl:otherwise>
</xsl:otherwise> 
</xsl:choose>
</xsl:template>

This works, however, I need another template for <desc> to cover all other occurrences of <desc> in the file that do not fall under the parameter.  I therefore have the following template:

<xsl:template match="desc">
  <fo:block margin-left="8em" font-style="italic" font-weight="normal">
   <xsl:apply-templates select="@* | *[contains(@type, $my_version) or string-length(@type)=0] | text()"/>
  </fo:block>
 </xsl:template> 

Unfortunately, the <desc> text that matches the  parameter is being output twice:  once in the pattern outlined in the parameter and once in the pattern outlined in the generic <desc> template.  How can I get the <desc> text matching the parameter to output only once (as outlined by the parameter) and still allow all other cases of the <desc> text to output as outlined by the generic "desc" template?

Thank you very much for any help that you may provide me.  I sincerely appreciate it!


Best wishes,
