RFC: [xsl] Recursive Template Improvements/Suggestions ??

Any suggestions for improvement would be greatly appreciated !!!

<script tag >

var btxt = "";                     // frame 3 table body text
function bt ( tg ) { btxt += tg; } // concatenate text function

// write table body frame 3
function body ( ) {
  bt('<html> ');

  ( ... )

  <  apply templates >

  ( ... )

   return btxt;
 } // end of table body frame 3

<end script tag>

<xsl:template match="/*/*/*" >
bt('<td align="center" nowrap="nowrap"> ');
<xsl:call-template name="repQuote">
  <xsl:with-param name="tbef" select="string('')"/>
  <xsl:with-param name="taft" select="."/>
  <xsl:with-param name="stop" select="0"/>
</xsl:call-template>
bt('</td> ');
</xsl:template>

Here is my XSL recursive template function:

<!-- recursive function to escape quote in -->
<!-- javaScript string literal assignment  -->
<xsl:template name="repQuote">
  <xsl:param name="tbef"/>
  <xsl:param name="taft"/>
  <xsl:param name="stop"/>
<xsl:choose>
<xsl:when test="$stop=0">
  <xsl:choose>
  <xsl:when test="contains($taft,'&quot;')">
    <xsl:variable name="xx">
      <xsl:value-of select="substring-before($taft,'&quot;')"/>
    </xsl:variable>
    <xsl:variable name="yy">
      <xsl:value-of select="substring-after($taft,'&quot;')"/>
    </xsl:variable>
    <xsl:variable name="zz">
      <xsl:value-of select="concat($xx,'\&quot;')"/>
    </xsl:variable>
    <xsl:call-template name="repQuote">
      <xsl:with-param name="tbef" select="concat($tbef,$zz)"/>
      <xsl:with-param name="taft" select="$yy"/>
      <xsl:with-param name="stop" select="0"/>
    </xsl:call-template>
  </xsl:when>
  <xsl:otherwise>
    <xsl:call-template name="repQuote">
      <xsl:with-param name="tbef" select="concat($tbef,$taft)"/>
       <xsl:with-param name="taft" select="string('')"/>
       <xsl:with-param name="stop" select="1"/>
     </xsl:call-template>
   </xsl:otherwise>
   </xsl:choose>
 </xsl:when>
 <xsl:otherwise>
   bt(&quot;<xsl:value-of select="$tbef"/>&quot;);
 </xsl:otherwise>
 </xsl:choose>
 </xsl:template>

Any suggestions for improvement would be greatly appreciated !!!

If you dig around in the archives, you'll find oodles of them.

The general principle works like this:

<xsl:template name="someTemplate">
  <xsl:param name="someParam"/>
  <!-- do some processing -->
  <xsl:if test="not(someStopCondition)"
    <xsl:call-template name="someTemplate">
      <xsl:with-param name="someParam" select="someValue"/>
    </xsl:call-template>
  </xsl:if>
</xsl:template>

Endless variations exist, but they all come down to the following
proposition: recuse as many times as needed until some stop condition is
met.

Spam:[xsl] Recursive Template ??






Is it possible to create a "recursive" template
that works in the same way as a recursive function call ???
