What is this gobbledygook??????
What processor are you using that you can get ANY result????
Why not just do
<xsl:template match ="/">
<html>
<body>
<xsl:for-each select="LOG/DIRECT/TARGET_CHARACTER_ID[. !=
preceding::TARGET_CHARACTER_ID]">
<xsl:sort select="." data-type="number"
order="ascending" />
<xsl:value-of select="position()" />. <xsl:value-of
select="." />
</xsl:for-each>
</body>
</html>
</xsl:template>
