[jira] Created: (TIKA-245) Support of CHM Format

Support of CHM Format
---------------------

                 Key: TIKA-245
                 URL: https://issues.apache.org/jira/browse/TIKA-245
             Project: Tika
          Issue Type: New Feature
          Components: parser
         Environment: All
            Reporter: Karl Heinz Marbaise
            Priority: Minor


It might be a good idea to support the CHM File format of Windows. Some information about http://en.wikipedia.org/wiki/Microsoft_Compiled_HTML_Help#Extracting_to_HTML. The CHM format contains HTML files which can be parsed by Tika. So the "only" problem is to extract the data from the CHM file.

See http://www.russotto.net/chm/chmformat.html for a description of the CHM format. Quick browsing didn't reveal any Java-based parser libraries that we could use to parse CHM files.

Hi, I've started to use TIKA to parse some files I have and sadly several of them are CHM. Have you tried http://sourceforge.net/projects/jchm/ to see it if works?

jchm looks promising, thanks for the pointer!

Is anyone interested in implementing a Tika Parser warpper for jchm? As a starting point it would be nice if the jchm jar was made available on Maven central.
