This patch introduces an extension to the current syntax for DOM index definition.
Specifically, it extends the 'index_subfields' tag to allow adding a 'condition'
attribute that is used as a condition ofr applying the specified index.
This (exotic) example is self-explanatory:
The previous syntax (which is keeped by this patch) took this snippet from biblio-koha-indexdefs.xml
<index_subfields tag="100" subfields="acbd">
<target_index>Encuadernador:w</target_index>
</index_subfields>
and generated an XSLT snippet in the DOM indexing XSLT that looks like this:
<xslo:for-each select="marc:subfield">
<xslo:if test="contains('acbd', @code)">
<z:index name="Encuadernador:w">
<xslo:value-of select="."/>
</z:index>
</xslo:if>
</xslo:for-each>
This patch introduces this syntax change (note the 'condition' attribute:
<index_subfields tag="100" subfields="acbd" condition="@ind2='7'">
<target_index>Encuadernador:w</target_index>
</index_subfields>
which yields to this XSLT snippet in the DOM indexing XSLT:
<xslo:if test="@ind2='7'">
<xslo:for-each select="marc:subfield">
<xslo:if test="contains('acbd', @code)">
<z:index name="Encuadernador:w">
<xslo:value-of select="."/>
</z:index>
</xslo:if>
</xslo:for-each>
</xslo:if>
To test:
- Verify that the shipped XSLT files are current regarding the shipped index definitions:
$ for i in marc21 normarc unimarc; do
xsltproc etc/zebradb/xsl/koha-indexdefs-to-zebra.xsl \
etc/zebradb/marc_defs/$i/biblios/biblio-koha-indexdefs.xml \
> etc/zebradb/marc_defs/$i/biblios/biblio-zebra-indexdefs.xsl
done
$ git status
(repeat for authorities, skip normarc which doesn't have authorities)
- Apply the patch
- Re-run the previous commands
=> SUCCESS: no changes
- Add a condition to an index_subfields tag (for example, condition="@ind2='7'" in the Author's index
- Regenerate the specific XSLT
=> SUCCESS: doing a diff shows the only change is the code has been wrapped inside an xslo:if using the condition for the test
- Apply the generated xsl to a MARCXML record that has a field matching the condition like this:
$ xsltproc .../biblio-zebra-indexdefs.xsl sample_record.xml
=> SUCCESS: There's an index on the result, containing the configured field/subfields, that matches the criteria.
- Sign off and feel really happy :-D
Note: the attached sample record includes a 100 field, with ind2=7 and $a=Tomasito
Edit: This patch was squashed once I figured it got too complex and Jonathan required a followup
to avoid code duplication.
This avoids code duplication, with the same results.
