One method is to test on preceding(-sibling) or following(-sibling) nodes:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:template match="Instruments|Equity">
<xsl:copy>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="*">
<xsl:if test="not(preceding-sibling::*[name()=name(current()) and
text()=current()/text()])">
<xsl:copy-of select="."/>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
Another method is to use keys for grouping with Muenchian Method:
