---------------------------------------

             Summary: ExternalParsers should allow dynamic keys to be specified for Regexs
                 Key: TIKA-1441
                 URL: https://issues.apache.org/jira/browse/TIKA-1441
             Project: Tika
          Issue Type: Bug
          Components: parser
         Environment: while working on TIKA-605 and memex
            Reporter: Chris A. Mattmann
            Assignee: Chris A. Mattmann
             Fix For: 1.7


While working on TIKA-605, I was trying to use ExternalParsers and I came across an interesting
use case. What if there are so many met keys that specifying all of them by hand as individual
regexs would be repetitive, and tedious. What if the met key itself could also be specified
by a regex, e.g., we just take the first group to be the key, and then the next group would
be the actual value? I ran across this in parsing GDAL output and so a very simple improvement
to the ExternalParsers Map<Pattern, String> map would be to allow it to take e.g., null
or "" Strings and then take that to mean that the Pattern specifies *both* the key name *and*
the key value.
I've got a patch I'll upload all tests pass and I need this to get TIKA-605 in and done.
