-----------------------------
Didn't search well enough apparently. This issue was already mentioned in
TIKA-1108.
> Different XML output structure for PPT and PPTX
> -----------------------------------------------
>
> Key: TIKA-1841
> URL: https://issues.apache.org/jira/browse/TIKA-1841
> Project: Tika
> Issue Type: Improvement
> Components: parser
> Affects Versions: 1.11
> Reporter: Sam H
>
> Issue is slightly related to TIKA-1840
> I've noticed that the XML structure of Powerpoint (PPT) and PPTX files is
> different.
> The structure for PPTX seems as follows:
> {code}
> <div class="slide-content"></div>
> <div class="slide-master-content" />
> <div class="slide-notes"></div> //optional
> <div class="slide-comment"></div> //optional
> ...
> <div class="slide-content"></div>
> <div class="slide-master-content" />
> <div class="slide-notes"></div> //optional
> <div class="slide-comment"></div> //optional
> {code}
> Note that there's no parent slide element to indicate the start and end of
> each slide.
> For powerpoint the structure is as follows:
> {code}
> <div class="slideShow">
> <div class="slide">
> <div class="slide-master-content"></div>
> <div class="slide-content"></div>
> <div class="slide-notes"></div> //added in TIKA-1840
> <div class="slide-comment"></div>
> </div>
> ...
> <div class="slide">
> <div class="slide-master-content"></div>
> <div class="slide-content"></div>
> <div class="slide-notes"></div> //added in TIKA-1840
> <div class="slide-comment"></div>
> </div>
> </div>
> <div class="slide-notes">
> {code}
> In my application, I'm using XPath to get the desired information . As the
> XML structure is different, I have to differentiate my XPath queries whether
> the file is PPT (old) or PPTX (new). It would be nice for Tika to return the
> same XML for both.
> I would propose changing the XML structure to this:
> {code}
> <div class="slideShow">
> <div class="slide">
> <div class="slide-master-content"></div>
> <div class="slide-content"></div>
> <div class="slide-notes"></div> //added in TIKA-1840
> <div class="slide-comment"></div>
> </div>
> ...
> <div class="slide">
> <div class="slide-master-content"></div>
> <div class="slide-content"></div>
> <div class="slide-notes"></div> //added in TIKA-1840
> <div class="slide-comment"></div>
> </div>
> </div>
> {code}
> So, essentially, like the current PPT output, but without the list of notes
> at the end (as this is also omitted for PPTX).
> On the one hand this generalizes PPT(X) handling, on the other it can break
> existing (external) functionality relying on a specific XML output format.
> I don't know if this is something the project wants fixed or not. If so, I'm
> willing to donate my time.
