    Thumbs up PARSE ANY FILE USING AUTO DETECT PARSER AND APACHE TIKA LIBRARY

    import org.apache.tika.exception.TikaException;

    import org.apache.tika.metadata.Metadata;

    import org.apache.tika.parser.AutoDetectParser;

    import org.apache.tika.sax.BodyContentHandler;

    import org.xml.sax.ContentHandler;

    import org.xml.sax.SAXException;

    import java.util.*;

    //Example :
    public class ParseFile
    {
    void parseDoc(final String resourceLocation) throws IOException,

    SAXException, TikaException {

    InputStream input = new FileInputStream(new File(resourceLocation));

    ContentHandler textHandler = new BodyContentHandler();

    Metadata metadata = new Metadata();

    AutoDetectParser parser = new AutoDetectParser();

    parser.parse(input, textHandler, metadata);

    input.close();

    out.println(“Tika Parser starts……\n”);

    out.println(“file name: “+resourceLocation);

    out.println(“Title: ” + metadata.get(“title”));

    out.println(“Author: ” + metadata.get(“Author”));

    out.println(“content: ” + textHandler.toString());

    out.println(“Tika Parser stops……”);
    }


    }

    public class AutoParse
    {

    public static void main(String[] args)
    {
    ParseFile pf=new ParseFile();
    Scanner sc=new Scanner();
    final String resourceLocation=sc.readLine();
    pf.parseDoc(resourceLocation);
    }
    }

    /*using this example we can parse any compatible file by calling parseDoc() providing file name in parameter (with location )

    In the above example, I first create a FileInputStream containing the document to parse. Then I use a Tika content handler called BodyContentHandler that internally construct s content handler decorator of type XHTML to TextContextHandler . The decorator is actually forming the plain text output from the SAX event that the Parser emits. Next I instantiate a AutoDetectParser directly, call the parse method and close the stream. It is required to call close method of InputStream since it is not the responsibility of Parser to call it for user.

    Tika provides some readymade ContentHandler implementations that can be useful while parsing content with Tika.

    Finally, the metadata (input/output) parameter provides additional data to the parser as input and can return additional metadata out from the document. Examples of metadata include things like author name, number of pages, creation date, etc.*/
    /* for Parsing image file

    ImageParser parser = new ImageParser();



    for parsing PDF

    PDFParser parser = new PDFParser();

    /*AutoDetectParser parser = newAutoDetectParser();

    Check the CAPs lock on your keyboard. All the letters in the title are uppercase.

    It's not a big deal.
    I think you should focus on importance of content rather than caps lock.

    Many find ALL CAPS annoying. Like shouting in a small room. It's considered rude behavior.

    Do you have a problem or question about the code?

    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE HERE
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
