Re: [xsl] removing duplicate elements based on two or more childs

[David Carlisle <davidc@xxxxxxxxx>]

    <xsl:template match="record">
        <xsl:if test="//term[not (. = preceding::term)]">
             <note>This is a new record</note>

the test here does not depend on the record element being matched
//term[not (. = preceding::term)] will have the same value wherever it
is evaluated in the document, and be true if there are any terms in
the document, and false otherwise.
In a boolean context it is the same as //term the predicate
[not (. = preceding::term)] is always true on the first term (if there
is a term)  


in xslt2 something like

<xsl:for-each-group select="record" group-by="string-join(
for $l in ('fra','eng') return lang[@id=$l]/term,':')">
 <xsl:copy-of select="."/>
</xsl:for-each-group>

would do what you ask, I think.

David
