It's quite complex our CHM Parser, can you apply a full fix and a test with
expected content in output on your file ?
Thanks,
> ChmDirectoryListingSet does not correctly enumerate directory entries

> Key: TIKA-1176
> URL: https://issues.apache.org/jira/browse/TIKA-1176
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 1.4
> Reporter: Doug Martin
> Attachments: HelpStudioSample.chm
>
>
> ChmDirectoryListingSet.enumerateOneSegment method does not correctly
> enumerate directory entries when ChmCommons.indexOf returns -1 for work data
> or user data. Here is the offending code:
> {code}
> int indexWorkData = ChmCommons.indexOf(dir_chunk,
> "::".getBytes());
> int indexUserData = ChmCommons.indexOf(dir_chunk,
> "/".getBytes());
> if (indexUserData < indexWorkData)
> setPlaceHolder(indexUserData);
> else
> setPlaceHolder(indexWorkData);
> if (getPlaceHolder() > 0 ...
> {code}
> If either indexUserData or indexWorkData is -1, that value will be set as the
> placeholder index, resulting in the method returning without processing any
> entries.
