How do I combine or merge grouped nodes?
- by LOlliffe
Using the XSL:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs" version="2.0">
<xsl:output method="xml"/>
<xsl:template match="/">
<records>
<record>
<!-- Group record by bigID, for further processing -->
<xsl:for-each-group select="records/record" group-by="bigID">
<xsl:sort select="bigID"/>
<xsl:for-each select="current-group()">
<!-- Create new combined record -->
<bigID>
<!-- <xsl:value-of select="."/> -->
<xsl:for-each select=".">
<xsl:value-of select="bigID"/>
</xsl:for-each>
</bigID>
<text>
<xsl:value-of select="text"/>
</text>
</xsl:for-each>
</xsl:for-each-group>
</record>
</records>
</xsl:template>
I'm trying to change:
<?xml version="1.0" encoding="UTF-8"?>
<records>
<record>
<bigID>123</bigID>
<text>Contains text for 123</text>
<bigID>456</bigID>
<text>Some 456 text</text>
<bigID>123</bigID>
<text>More 123 text</text>
<bigID>123</bigID>
<text>Yet more 123 text</text>
</record>
into:
<?xml version="1.0" encoding="UTF-8"?>
<records>
<record>
<bigID>123</bigID>
<text>Contains text for 123</text>
<text>More 123 text</text>
<text>Yet more 123 text</text>
</bigID>
<bigID>456
<text>Some 456 text</text>
</bigID>
</record>
Right now, I'm just listing the grouped <bigIDs, individually. I'm missing the step after grouping, where I combine the grouped <bigID nodes. My suspicion is that I need to use the "key" function somehow, but I'm not sure.
Thanks for any help.
