I need some assistance converting an xml document to a CSV file using an xslt stylesheet. I am trying to use the following xsl and I can't seem to get it right. I want my comma delimited file to include column headings, followed by the data. My biggest issues are removing the final comma after the last item and inserting a carriage return so each group of data appears on a separate line. I have been using XML Notepad.

  <xsl:template match="/">
        <xsl:element name="table">
              <xsl:apply-templates select="/*/*[1]" mode="header" />
              <xsl:apply-templates select="/*/*" mode="row" />
        </xsl:element>
  </xsl:template>

  <xsl:template match="*" mode="header">
        <xsl:element name="tr">
              <xsl:apply-templates select="./*" mode="column" />
        </xsl:element>
  </xsl:template>

  <xsl:template match="*" mode="row">
        <xsl:element name="tr">
              <xsl:apply-templates select="./*" mode="node" />
        </xsl:element>
  </xsl:template>

  <xsl:template match="*" mode="column">
        <xsl:element name="th">
              <xsl:value-of select="translate(name(.),'qwertyuiopasdfghjklzxcvbnm_','QWERTYUIOPASDFGHJKLZXCVBNM ')" />
        </xsl:element>,
  </xsl:template>

  <xsl:template match="*" mode="node">
        <xsl:element name="td">
              <xsl:value-of select="." />
        </xsl:element>,
  </xsl:template>
