Problems handling Hyperlinks and Tables in Word 97 Docs

                 Key: TIKA-405
                 URL: https://issues.apache.org/jira/browse/TIKA-405
             Project: Tika
          Issue Type: Bug
    Affects Versions: 0.7
         Environment: 32-bit Ubuntu Linux
            Reporter: Curtis Warner

I discovered some odd behavior while running a three-way comparison test between Tika, Aperture,
and Autonomy KeyView. The input file was a test Word 97 Doc (attached) including a paragraph
peppered with hyperlinks and a table filled with dummy text. KeyView generated the full text,
as I expected. Aperture and Tika had identical results to one another (barring one lost whitespace
character), but their outputs yielded significantly fewer tokens than KeyView's did. I've
attached the output text from KeyView and Tika for reference.

There are two distinct problems I recognized in Tika's text output:

1) Hyperlinks from the Word Doc aren't included in the output text. They appear to have been
skipped completely.

2) The values in the Word Doc's table are conglomerated all together into a single blob rather
than being emitted separately, which ruins any attempt at tokenizing the table's contents.

Seeing as both Tika and Aperture had exactly the same issues with this test file, my guess
is that it's a problem with the shared POI library. I thought it would be worth noting, though,
in case there's an easy fix on the Tika end of things.
