HSLF vs. XSLF

I have to do some automated power point modifications to an existing 
template file (PPTX, although it has no PPTX features being used).   
What I need to do is find and duplicate slides, find and replace text, 
insert a couple of graphics (bar, pie charts).  The "master" is nicely 
setup, with various types of master templates.

At this point, is it worth working with XSLF if no features are being 
used?  Or am I better off sticking with OLE for now until we can improve 
XSLF further?

Thanks.

Aram

I think the best XSLF examples are unit tests:

Only for text extraction:
http://svn.apache.org/repos/asf/tika/trunk/tika-parsers/src/main/java/org/apache/tika/parser/microsoft/ooxml/XSLFPowerPointExtractorDecorator.java

I think Yegor has been doing quite a bit of work lately on writing / 
editing .pptx files, hence the recent commits of his to improve XSLF!

Thanks nick, exactly what I needed.   Do you have any code (other than 
the 1 example) that is using XSLF?

You'll likely find that HSLF is better developed than XSLF in terms of 
features, but that adding new features is easier with XSLF than HSLF. 
It'll largely depend therefore on how many patches to POI you expect 
you'll end up needing to write and contribute back! :)
