Norconex Importer is a Java library and command-line application meant to "parse" and "extract" content out of a file as plain text, whatever its format (HTML, PDF, Word, etc).

DomTagger does not respect overwrite=true #90

Closed ohtwadi closed 4 years ago

ohtwadi commented 5 years ago

Hello,

I wanted to set the title to a specific div, but noticed that using the DOMTagger with overwrite="true" actually appends the new value to the existing value in title field.

<preParseHandlers>
  <tagger class="com.norconex.importer.handler.tagger.impl.DOMTagger">
    <dom selector="div#ArticleDetailTitle" toField="title" overwrite="true"/>
  </tagger>
</preParseHandlers>

I'm working around this by copying to a temp field and then copying that temp field to the actual title field. CopyTagger respects overwrite=true just fine.

<postParseHandlers>
  <tagger class="com.norconex.importer.handler.tagger.impl.DOMTagger">
    <dom selector="div#ArticleDetailTitle" toField="title-temp" overwrite="true"/>
  </tagger>

  <tagger class="com.norconex.importer.handler.tagger.impl.CopyTagger">
    <copy fromField="title-temp"    toField="title" overwrite="true" />
  </tagger>
</postParseHandlers>

I suspect it works, but a title gets added when the document is parsed and a title is extracted (adding to the one you created with DOMTagger. Your workaround is a good one, or you can also look at ForceSingleValueTagger as a post-parse handler.
