CSV to XML

Hi all, 

I know how to convert this CSV file into Xml one by
this XSL file in XSLT2.0. 

1. CSV file: 
X1,X1,X2,X2,X2,X3
a1,a2,a3,a4,a5,a6

2. XSL file: 
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">
        <xsl:variable name="csv"
select="unparsed-text('target.csv')"/>
        <xsl:output method="xml" indent="yes"/>
        <xsl:variable name="splitLines"
select="tokenize($csv, '&#xA;')"/>
        <xsl:variable name="columnNames"
select="tokenize($splitLines[1], ',')"/>

        <xsl:template match="/">
             <users>
                <xsl:for-each
select="$splitLines[position() &gt; 2]">
                    <xsl:variable name="a"
select="position()"/>
                    <xsl:call-template name="Line">
                        <xsl:with-param
name="columnNames" select="$columnNames" />
                        <xsl:with-param name="cells"
select="$splitLines[$a+1]" />
                    </xsl:call-template>
                </xsl:for-each>
             </users>
        </xsl:template>

        <xsl:template name="Line">
                <xsl:param name="columnNames"/>
                <xsl:param name="cells"/>
                <xsl:variable name="cellValues"
select="tokenize($cells, ',')"/>

                <xsl:for-each
select="$cellValues[position()]">
                    <xsl:variable name="a"
select="position()"/>
                    <tab>
                        <xsl:attribute name="name">
                                <xsl:value-of
select="normalize-space($columnNames[$a])"/>
                        </xsl:attribute>
                        <sub>
                                <xsl:value-of
select="normalize-space($cellValues[$a])"/>
                        </sub>
                    </tab>
                </xsl:for-each>
        </xsl:template>
</xsl:stylesheet>

3. XML output. 
<?xml version="1.0" encoding="UTF-8"?>
<users>
   <tab name="X1">
      <sub>a1</sub>
   </tab>
   <tab name="X1">
      <sub>a2</sub>
   </tab>
   <tab name="X2">
      <sub>a3</sub>
   </tab>
   <tab name="X2">
      <sub>a4</sub>
   </tab>
   <tab name="X2">
      <sub>a5</sub>
   </tab>
   <tab name="X3">
      <sub>a6</sub>
   </tab>
</users>

Now the CSV file has been changed to as: 
"
X1,,X2,,,X3
a1,a2,a3,a4,a5,a6
"
and is expeting the same XML output... I am blocked.
So can someone give me some help for this ? 

 

Thanks a lot 


Chun
