Android Question [Request] Apache Tika Lib/Wrap, Extract structured text from different file types

The Apache Tika™ toolkit detects and extracts metadata and text from over a thousand different file types (such as PPT, XLS, and PDF). All of these file types can be parsed through a single interface, making Tika useful for search engine indexing, content analysis, translation, and much more.

The Parser interface is the key concept of Apache Tika. It hides the complexity of different file formats and parsing libraries while providing a simple and powerful mechanism for client applications to extract structured text content and metadata from all sorts of documents. All this is achieved with a single method:

B4X:

void parse(
   InputStream stream, ContentHandler handler, Metadata metadata,
   ParseContext context) throws IOException, SAXException, TikaException;

The parse method takes the document to be parsed and related metadata as input and outputs the results as XHTML SAX events and extra metadata. The parse context argument is used to specify context information (like the current local) that is not related to any individual document.
