问题描述 (Problem Description)

如何使用java从ODF中提取内容。

解决方案 (Solution)

以下是使用java从ODF中提取内容的程序。

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
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: IOWIKI 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.
