For more control, you can call the Tika Parsers directly. Most likely, you'll want to start out using the Auto-Detect Parser , which automatically figures out what kind of content you have, then calls the appropriate parser for you. With Tika, you can get the textual content of your files returned in a number of different formats.
These can be plain text, html, xhtml, xhtml of one part of the file etc. This is controlled based on the ContentHandler you supply to the Parser. By using the BodyContentHandler , you can request that Tika return only the content of the document's body as a plain-text string.
It is possible to customise your parsing by supplying your own ContentHandler which does special things. By using the PhoneExtractingContentHandler , you can have any phone numbers found in the textual content of the document extracted and placed into the Metadata object for you. Sometimes, you want to chunk the resulting text up, perhaps to output as you go minimising memory use, perhaps to output to HDFS files, or any other reason!
