I'm working with xsl keys and I want to get exclude repeated element values, I have the following xml:
<?xml version="1.0" encoding="utf-8" ?>
<root>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
.....
xmlns:xml="http://www.w3.org/XML/1998/namespace">
<skos:Concept rdf:about="http://aims.fao.org/aos/agrovoc/c_26321">
.....
<skos:prefLabel xml:lang="en">Abies mariesii</skos:prefLabel>
.....
<skos:broader rdf:resource="http://aims.fao.org/aos/agrovoc/c_10"/>
</skos:Concept>
<skos:Concept rdf:about="http://aims.fao.org/aos/agrovoc/c_33272">
.....
<skos:prefLabel xml:lang="en">Abies numidica</skos:prefLabel>
.....
<skos:broader rdf:resource="http://aims.fao.org/aos/agrovoc/c_10"/>
</skos:Concept>
<skos:Concept rdf:about="http://aims.fao.org/skosmos/agrovoc/en/page/c_10">
.....
<skos:narrower rdf:resource="http://aims.fao.org/skosmos/agrovoc/en/page/c_26321"/>
.....
</skos:Concept>
</rdf:RDF>
Please take note that the skos:broader rdf:resource="http://aims.fao.org/aos/agrovoc/c_10" which is a child of skos:Concept has been repeated many times in the document and the full file can be accessed here: 128.199.159.143/merged-file.xml.
I am using the following xslt which was based from xslt get element value based on attribute which is referenced in another node tree using keys to output my file into text:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
.....
xmlns:void="http://rdfs.org/ns/void#">
<xsl:output method="text" omit-xml-declaration="yes" indent="no"/>
<xsl:key name="concepts-by-about" match="//skos:Concept" use="@rdf:about" />
<xsl:template match="root">
<xsl:for-each select="rdf:RDF">
<xsl:text>START HERE</xsl:text>
<xsl:text> </xsl:text>
<xsl:text>=LDR 00000nam 2200000Ia 4500</xsl:text>
<xsl:text> </xsl:text>
....
<xsl:apply-templates select="skos:Concept" />
<xsl:text> </xsl:text>
....
<xsl:apply-templates select="skos:Concept/skos:narrower" />
<xsl:text> </xsl:text>
<xsl:apply-templates select="skos:Concept/skos:broader" />
<xsl:text> </xsl:text>
</xsl:for-each>
</xsl:template>
<xsl:template match="skos:Concept/skos:broader[key('concepts-by-about', @rdf:resource)]">
<xsl:text>=301 \\$abroader$b</xsl:text>
<xsl:value-of select="key('concepts-by-about', @rdf:resource)/skos:prefLabel[@xml:lang='en']" />
<xsl:text>$c</xsl:text>
<xsl:value-of select="./@rdf:resource" />
<xsl:text> </xsl:text>
</xsl:template>
<xsl:template match="text()" />
<xsl:template match="//skos:narrower[key('concepts-by-about', @rdf:resource)]">
<xsl:text>=302 \\$anarrower$b</xsl:text>
<xsl:value-of select="key('concepts-by-about', @rdf:resource)/skos:prefLabel[@xml:lang='en']" />
<xsl:text>$c</xsl:text>
<xsl:value-of select="./@rdf:resource" />
<xsl:text> </xsl:text>
</xsl:template>
<xsl:template match="text()" />
</xsl:stylesheet>
With this xslt I'm getting numerous =301 \$abroader$bAbies$chttp://aims.fao.org/aos/agrovoc/c_10. Sample file printed is below:
START HERE
=LDR 00000nam 2200000Ia 4500
....
=302 \\$anarrower$bAbies$chttp://aims.fao.org/aos/agrovoc/c_10
....
=302 \\$anarrower$bAbies pinsapo$chttp://aims.fao.org/aos/agrovoc/c_34587
=302 \\$anarrower$bAbies alba$chttp://aims.fao.org/aos/agrovoc/c_11
....
=301 \\$abroader$bAbies$chttp://aims.fao.org/aos/agrovoc/c_10
So my question is how do I exclude the repeated values or is there a way to output these repeated values in one line, like below:
=310 \\$abroader$bAbies$chttp://aims.fao.org/aos/agrovoc/c_10
Thanks in advance and cheers!
