My XML structure was basically:
<PARAGRAPH style='heading1' emphasis='true' font='arial' number='30' indent=’10’><SPECIALTEXT style='heading1' emphasis='true' font='arial' number='31'>
Helloworld</SPECIALTEXT>
</PARAGRAPH>Output needed to be:
<PARAGRAPH style='heading1' emphasis='true' font='arial' number='30'>
Helloworld</PARAGRAPH>
Now this only works on the first level after the PARAGRAPH but that’s all I needed, and it could be changed to do this recursively I guess. Basically I am matching on any paragraph that contains a child element SPECIALTEXT with the same style attribute and calling the template CompareKeyAttributes.
PARAGRAPH has more attributes than SPECIALTEXT in most cases so I compare only the ones that exist in SPECIALTEXT.
CompareKeyAttributes will return a string of all the
attributes that don’t match so then I just check if I care that the attribute
is different and output accordingly.
<xsl:template match="PARAGRAPH[SPECIALTEXT[@Style=./@Style] ] ">
<xsl:copy>
<xsl:apply-templates select="@*"/><xsl:for-each select=" child::*">
<xsl:variable name="RESULT"><xsl:call-template name="CompareKeyAttributes">
<xsl:with-param name="PARA" select=".."/><xsl:with-param name="SPEC" select="."/>
</xsl:call-template></xsl:variable>
<xsl:choose>
<xsl:whentest="$RESULT='number' "><xsl:apply-templates select="child::node()"/>
</xsl:when><xsl:otherwise>
<xsl:copy><xsl:apply-templates select="@*|node()"/>
</xsl:copy></xsl:otherwise>
</xsl:choose></xsl:for-each>
</xsl:copy>
</xsl:template><xsl:template name="CompareKeyAttributes">
<xsl:param name="PARA"/>
<xsl:param name="SPEC"/><xsl:for-each select="$SPEC/@*">
<xsl:variable name="SPEC_ATT" select="name()"/><xsl:variable name="PARA_ATT" select="$PARA/@*[name()= $SPEC_ATT]"/>
<xsl:choose><xsl:when test="$PARA_ATT != .">
<xsl:value-of select="name()"/></xsl:when>
</xsl:choose>
</xsl:for-each></xsl:template>
Let me know if you find this useful or have anyway to make it better. Enjoy
