I am trying to produce output like this:

01/01/2007  Something for january 1st
            Something else for january 1st
            And another for january 1st
05/01/2007  A data row for january 5th
            And another for january 5th

And I'm using code like this:
<xsl:for-each select="transactions/transdet">
  <xsl:sort select="lduk_vp_date"/>
    <tr valign="top">
      <td align="left">
        <xsl:if test="lduk_vp_date != preceding-sibling::*[1]/
lduk_vp_date">
          <xsl:call-template name="shortdate">
            <xsl:with-param name="datetime">
              <xsl:value-of select="lduk_vp_date"/>
            </xsl:with-param>
          </xsl:call-template>
        </xsl:if>
      </td>
etc.

This is KIND OF working, but I've realised that my date field
(lduk_vp_date) contains a time component too, but I'm not interested
in the time.  My output is therefore looking like this:
01/01/2007 00:01:15 Something for january 1st
01/01/2007 06:23:05 Something else for january 1st
01/01/2007 07:01:11 And another for january 1st
05/01/2007 06:45:22 A data row for january 5th
05/01/2007 06:45:25 And another for january 5th

Is there anything I can do to avoid this?  I'm restricted to XSL
Version1 unfortunately.

Thanks
