Hi,

This should do it without recursion:


//put this template in between your <td> and </td>
//remember to change $yourTextString (!)

<xsl:call-template name="text_wrapper">
   <xsl:with-param name="Text" select="$yourTextString"/>
</xsl:call-template>

//this will display the first 30 chars of $Text then pass the rest to
wrapper_helper
//if no string is left it will stop
<xsl:template name="text_wrapper">
<xsl:param name="Text"/>
<xsl:choose>
    <xsl:when test="string-length($Text)">
      <xsl:value-of select="substring($Text,1,30)"/><br/>
      <xsl:call-template name="wrapper_helper">
        <xsl:with-param name="Text" select="substring($Text,31)"/>
      </xsl:call-template>
    </xsl:when>
    <xsl:otherwise>
      no more string!
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>

//this will also display 30 chars of the string, and pass the rest back to
text_wrapper
<xsl:template name="wrapper_helper">
<xsl:param name="Text"/>
  <xsl:value-of select="substring($Text,1,30)"/><br/>
  <xsl:call-template name="text_wrapper">
    <xsl:with-param name="Text" select="substring($Text,31)"/>
  </xsl:call-template>
</xsl:template>



Cheers
