以下は、javaを使用してODFからコンテンツを抽出するプログラムです。

import org.apache.tika.exception.TikaException;
import org.apache.tika.metadata.Metadata;
import org.apache.tika.parser.ParseContext;
import org.apache.tika.parser.odf.OpenDocumentParser;
import org.apache.tika.sax.BodyContentHandler;
import org.xml.sax.SAXException;

public class ExtractContentFromODF {
   public static void main(String[] args) throws Exception {

     //detecting the file type
      BodyContentHandler handler = new BodyContentHandler();

      Metadata metadata = new Metadata();
      FileInputStream inputstream = new FileInputStream(new File(
         "C:/tika/odfExample.odt"));
      ParseContext pcontext = new ParseContext();

     //Open Document Parser
      OpenDocumentParser openofficeparser = new OpenDocumentParser ();

      openofficeparser.parse(inputstream, handler, metadata,pcontext);
      System.out.println("Contents of the document:" + handler.toString());
      System.out.println("Metadata of the document:");
      String[] metadataNames = metadata.names();

      for(String name : metadataNames) {
         System.out.println(name + " :  " + metadata.get(name));
      }
   }
}

Contents of the document: Tutorials Point originated from the idea that there exists a
class of readers who respond better to online content and prefer to learn new skills
at their own pace from the comforts of their drawing rooms.

The journey commenced with a single tutorial on HTML in 2006 and elated by the response
it generated, we worked our way to adding fresh tutorials to our repository which now
proudly flaunts a wealth of tutorials and allied articles on topics ranging from
programming languages to web designing to academics and much more.
