Tomas Cohen Arazi 5d46dbf3e9 Bug 14217: Add 'condition' attribute for DOM index definition
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.

This file has been automatically generated from a Koha index definition file
with the stylesheet koha-indexdefs-to-zebra.xsl. Do not manually edit this file,
as it may be overwritten. To regenerate, edit the appropriate Koha index
definition file (probably something like {biblio,authority}-koha-indexdefs.xml) and run:
`xsltproc koha-indexdefs-to-zebra.xsl {biblio,authority}-koha-indexdefs.xml >
{biblio,authority}-zebra-indexdefs.xsl` (substituting the appropriate file names).
