Thanks for any tips how to improve performance..
<xsl:variable name="identifier">
<xsl:value-of select="normalize-space(dc:identifier)"/>
</xsl:variable>
Never use an xsl:variable with content like this unless you really need
to generate a new result tree fragment 9which is essentially a new node
tree with a root node (/) a text node with string value. that's
expensive to build and has to be coersed back to a string when used. You
just want a string here so
<xsl:variable name="identifier">
select="normalize-space(dc:identifier)"/>
which is less code to type and a lot more efficient (athough in this
case you don't really need a variable at all). In xslt1 that will use
the first dc:identifier, in xslt2 it will generate an error that there
is more than one. Tou sie the second you can use
<xsl:variable name="identifier">
select="normalize-space(dc:identifier[2])"/>
or [last()] or whatever predicate you need to specify.
<rdf:Description>
<xsl:attribute name="rdf:about"><xsl:value-of
select="$identifier"/></xsl:attribute>
could be written more simply as
<rdf:Description rdf:about="{$identifier}">
or just inline the variable if it is only used once:
<rdf:Description rdf:about="{normalize-space(dc:identifier[2]}">
