Hi All,
I have an XML file with parts similar to this:
<?xml version="1.0" encoding="UTF-8"?>
<parts>
<part no="123456" desc="HOSE KIT"/>
<part no="234567" desc="HOSE FITTINGS"/>
<part no="345678" desc="HOSE SEGMENT"/>
</parts>
When processing the parts with XSLT 2, I want to filter out some of
the parts based on words or phrases that the user supplies. I was
thinking of a lookup XML file that they could maintain:
<?xml version="1.0" encoding="UTF-8"?>
<exclude>
<exclude>FITTINGS</exclude>
<exclude>SEGMENT</exclude>
</exclude>
This is a roughed out stylesheet, but I am not sure the best way to
use the look up. I could convert the <exclude> elements to a regular
expression and apply it to the @desc attribute, but I am not sure if
there is a better approach that I am missing.
<?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:variable name="exclude" select="doc('excludes.xml')"/>
<xsl:template match="/parts">
<xsl:apply-templates/>
</xsl:template>
If you add an empty template
<xsl:template match="part[some $exclude in $exclude/exclude/exclude
satisifes matches(@desc, $exclude) ]"/>
then any matched "part"s will not be processed, for the rest you can set
up the identity transformation. Or you can of course use any such
predicate in an apply-templates e.g.
<xsl:apply-templates select="part[not(some $exclude in
$exclude/exclude/exclude satisifes matches(@desc, $exclude))]"/>
