Hi Zab,
Have you tried TikaInputStream?
Here is a snippet with AutoDetectParser-
Initialize
-------------------
this.context = new ParseContext();
this.parser = new AutoDetectParser();
this.context.set(Parser.class, parser);
Parse
---------
// create a string writer object
StringWriter textBuffer = new StringWriter();
// get the Tika Input Stream from the input stream to target file
InputStream stream = TikaInputStream.get(inStream);
// create a content handler
ContentHandler handler = new TeeContentHandler(
getTextContentHandler(textBuffer));
// create metadata object
Metadata metadata = new Metadata();
try {
// parse the document
parser.parse(stream, handler, metadata, context);
// return the parsed text
return textBuffer.toString();
} catch (SAXException ex) {
// log the exception
LOG.error(ex.getMessage());
// throw as IOException
throw new IOException(ex);
} catch (TikaException ex) {
// log the exception
LOG.error(ex.getMessage());
ex.printStackTrace();
// throw as IOException
throw new IOException(ex);
} finally {
if (stream != null) {
// close the stream
stream.close();
}
}
Regards,
Anuj
