RE: [xsl] A unique distinct problem

["Evan Lenz" <elenz at xyzfind dot com>]

I think this should work for you:

<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

  <xsl:output indent="yes"/>

  <xsl:template match="/">
    <xsl:apply-templates
select="/report/subscriber/location/shift_date[not(@date=preceding::shift_da
te/@date)]">
      <xsl:sort select="@date"/>
    </xsl:apply-templates>
  </xsl:template>

  <xsl:template match="shift_date">
    <xsl:copy>
      <xsl:copy-of select="@*"/>
      <xsl:apply-templates
select="/report/subscriber/location/shift_date[@date=current()/@date]/credit
_card[not(@type=preceding::credit_card[../@date=current()/@date]/@type)]"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="credit_card">
    <xsl:copy>
      <xsl:copy-of select="@*"/>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>
