[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] swapping context, a grouping problem.
 I'm processing some stuff that is derived from db tables.
The main content (input document) is of the form
<doc>
<entry>
<cat>category number </cat>
<section>section number </section>
</entry>
</doc>
For grouping, I have two other files cat.xml and section.xml
cat.xml (the cat numbers increment from 1)
<doc>
<entry>
<cat>cat number</cat>
<ttl>category title </ttl>
</entry
</doc>
and section.xml
<doc>
<entry>
<section>section number</section>
<ttl>section title</ttl>
</entry>
</doc>
Its a case of grouping them by category and section to provide
<cat>
<hd>Category title </hd>
<sect>
<hd>Section title </hd>
<entry>
...
</entry
I.e. to group by category then section.
with context doc in the main file I have
<xsl:template name="catSequence">
<xsl:param name="cats" select="document('category.xml')/doc"/>
<xsl:param name="idx" select="1"/>
<xsl:if test="$idx <= count($cats/entry)">
<xsl:variable name="thisCat" select="$cats/entry[$idx]/categoryID"/>
<!-- All entries in this category -->
<xsl:variable name="ents" select="entry[cat=$thisCat]"/>
<category><head><xsl:value-of
select="$cats/entry[categoryID=$thisCat]/category_Nam"/></head>
<section>
<xsl:for-each
select="document('section.xml')/doc/entry[categoryID=$thisCat]">
<xsl:copy-of
select="key('catandsection',concat(cat,'and',SectionID))"/>
</xsl:for-each>
</section>
</category>
<xsl:call-template name="catSequence">
<xsl:with-param name="idx" select="$idx + 1"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
<xsl:key name="cat"
match="entry"
use="cat"/>
<xsl:key name="catandsection"
match="entry"
use="concat(cat, 'and', SectionID)"/>
the problem is that the keys are operating in a different document,
hence the context is wrong to copy the entries through from the main source
file.
I can't figure a way of getting the section titles without iterating through
them (in the sections.xml document) which screws the context up for the rest
of
the processing.
Any help appreciated.
