Makros and if-conditionals

[TobiasNx]

At the moment you cannot use makros in if-conditionals but also you also cannot create an makro that is only the if-conditional.

In context of lobid ressources - ALMA we needed to check for duplicates and wanted to reuse a small marko that we do not need to write the if-conditional again and again:

  <macro name="ignoreLocalExtensions">
      <if>
        <none flushWith="$[dsource][01] " sameEntity="true">
          <data name="" source="$[dsource][01] .M" />
        </none>
      </if>
  </macro>

That did not work with:

    <entity name="" flushWith="100[01] " sameEntity="true">
      <call-macro name="ignoreLocalExtensions" field="100" />
    ... 
    </entity> 

We received:

Caused by: org.xml.sax.SAXParseException; systemId: file:/home/tobias/git/lobid-resources/src/main/resources/alma/macros.xml; lineNumber: 159; columnNumber: 11; cvc-complex-type.2.4.a: Invalid content was found starting with element 'if'. One of '{"http://www.culturegraph.org/metamorph":group, "http://www.culturegraph.org/metamorph":data, "http://www.culturegraph.org/metamorph":all, "http://www.culturegraph.org/metamorph":any, "http://www.culturegraph.org/metamorph":choose, "http://www.culturegraph.org/metamorph":combine, "http://www.culturegraph.org/metamorph":concat, "http://www.culturegraph.org/metamorph":none, "http://www.culturegraph.org/metamorph":square, "http://www.culturegraph.org/metamorph":tuples, "http://www.culturegraph.org/metamorph":range, "http://www.culturegraph.org/metamorph":equalsFilter, "http://www.culturegraph.org/metamorph":containsFilter, "http://www.culturegraph.org/metamorph":entity}' is expected.

Then we tried to create a makro for the condition of the if-conditional:

  <macro name="ignoreLocalExtensions">
        <none flushWith="$[dsource][01] " sameEntity="true">
          <data name="" source="$[dsource][01] .M" />
        </none>
  </macro>

That did not work with:

    <entity name="" flushWith="100[01] " sameEntity="true">
        <if>
          <call-macro name="ignoreLocalExtensions" field="100" />
       </if>
    ... 
    </entity> 

We received:

We discussed how easily implement at least one form of combining if-conditionals and makros. At the moment it seems that the option to allow makros in an if-conditional as we tried in our second attempt seems to be the easiest.
