---------------------------------------
Summary: lower magic priority xhtml magic priority to ensure
emails detected as message/rfc822
Key: TIKA-1771
URL: https://issues.apache.org/jira/browse/TIKA-1771
Project: Tika
Issue Type: Improvement
Components: detector
Reporter: Jeremy B. Merrill
Priority: Critical
Emails I have (happy to share if you want) contain XHTML, as one part of a
multipart email. Prior to this pull request, the priority on the
application/xhtml+xml magic detector was 50, equal to the priority on the
message/rfc822 detector. Because of the relative position of the two detectors
in tika-mimetypes.xml, the emails were incorrectly detected as XHTML documents.
With this PR, by downgrading the priority of application/xhtml+xml to 40, the
more-sensitive email magic detectors take precedence, causing the emails to be
properly detected as message/rfc822.
I have not run this thru the govdocs tester or anything other than my own
documents, so, full disclosure, this could cause false negative
xhtml-detections elsewhere.
