Re: Simple XPath question

["Nikita Ogievetsky" <nogievet@xxxxxxxxxxxx>]

You are right. I did this in a rush and missed this case.
The following constructs works with your fragment correctly:

  <xsl:for-each select="PERSON">
    <xsl:if test="following-sibling::PERSON[current()/@lastname =
./@lastname and current()/@firstname = ./@firstname]">
       <xsl:if test="not(preceding-sibling::PERSON[current()/@lastname =
./@lastname and current()/@firstname = ./@firstname])">
          <xsl:copy-of select="."/>
       </xsl:if>
    </xsl:if>
  </xsl:for-each>

applied to your fragment it gives:

<PERSON firstname="fn1" lastname="ln1"/>
