Tika Parser: Exclude PDF Attachments

Question

Answer 1

Implement a custom org.apache.tika.extractor.DocumentSelector and set it at the ParseContext. The DocumentSelector is called with metadata of the embedded document to decide whether the embedded document should be parsed.

Example DocumentSelector:

public class CustomDocumentSelector implements DocumentSelector {

  @Override
  public boolean select(Metadata metadata) {
    String resourceName = metadata.get(Metadata.RESOURCE_NAME_KEY);
    return resourceName == null || !resourceName.endsWith(".joboptions");
  }
}

Register it at the ParseContext:

parseContext.set(DocumentSelector.class, new CustomDocumentSelector());
