Backup plan for parsing
-----------------------
Key: TIKA-669
URL: https://issues.apache.org/jira/browse/TIKA-669
Project: Tika
Issue Type: New Feature
Components: parser
Reporter: Jukka Zitting
Currently once a document type has been detected we direct the document to the
one parser that best matches the detected type. In practice there are cases
where that parser finds that it in fact cannot parse this document, for example
when something that looked like XML turns out to have syntax errors. For such
cases it would be nice if the CompositeParser could then retry parsing the
document with a more generic backup parser, like the plain text parser for
malformed XML.
Implementing this would require some level of buffering and redirection of both
parser input and output. Input buffering is easy, but for output buffering we'd
probably need to implement new ContentHandler and Metadata layers.
