     //Text document parser
      TXTParser  TexTParser = new TXTParser();

      TexTParser.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();

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.
