Re: [xsl] String extraction

Hi Sven,
  Please try this XSL -

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:output method="html" indent="yes"/>
	
<xsl:template match="/top">
  <xsl:variable name="str1"
select="substring-before(., '(')"/>
  <xsl:variable name="str2">
    <xsl:choose>
      <xsl:when test="contains(substring-after(.,
'('), ',')">
        <xsl:value-of
select="substring-before(substring-after(., '('),
',')"/>
      </xsl:when>
      <xsl:otherwise>
	<xsl:value-of
select="substring-before(substring-after(., '('),
')')"/>
      </xsl:otherwise>
    </xsl:choose>
   </xsl:variable>
   <xsl:variable name="str3"
select="substring-before(substring-after(., ','),
')')"/>		
   <html>
     <head>
       <title/>
     </head>
     <body>
       <table>
	 <tr>
	   <td>
	     <xsl:value-of select="$str1"/>
	   </td>
	   <td>
	     <xsl:value-of select="$str2"/>
	   </td>
	 </tr>
	 <xsl:call-template name="generateTRs">
	   <xsl:with-param name="str" select="$str3"/>
	   <xsl:with-param name="delim" select="','"/>
	 </xsl:call-template>
       </table>
     </body>
   </html>
</xsl:template>
	
<!-- a recursive template to generate <tr>s -->
<xsl:template name="generateTRs">
  <xsl:param name="str"/>
  <xsl:param name="delim"/>
  
  <xsl:choose>
    <xsl:when test="contains($str, ',')">
      <tr>
       <td/>
       <td>
	 <xsl:value-of select="substring-before($str, ',')"/>
       </td>
      </tr>
      <xsl:call-template name="generateTRs">
	<xsl:with-param name="str"
select="substring-after($str, ',')"/>
	<xsl:with-param name="delim" select="$delim"/>
      </xsl:call-template>
    </xsl:when>
    <xsl:otherwise>
      <tr>
	<td/>
	<td>
	  <xsl:value-of select="$str"/>
	</td>
      </tr>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>

</xsl:stylesheet>
