David Spencer commented on NUTCH-21:
------------------------------------
This may be of some use:
I needed a PPT parser in the context of Lucene, so I copied the code from here,
commented out a few nutch-specific things (e.g. the logging calls), and tested
it on some local PPT files. I'm using POI-2.5.1-final.
The code is not perfect, nor is the PPT I have :) but it's pretty good.
When it works it works well.
Went it fails it sometimes says there is no content, but in the doc I spot
checked there seemed to be textual content. I have only spot checked a few docs
but I did run it thru my disk:
In a test run:
[a] I had 195 PPT files
[b] In 36 files it said there was no body
[c] With one file it thru an exception
[d] With 158 files it found content
Wrt [b] this is not necessarily wrong e.g. if there are only images, however in
the 1 file I spot checked there was apparently textual content.
Wrt [d], I didn't spot check many files but the ones I did seemed fine.
Personally I would advocate using this esp if someone verifies this within
nutch - but I'm confident it will work as I didn't change much to use it in
Lucene.
This was the "bug" that happened in 1 file
