Multiple Relationships in pptx4j

by **Jim** » Fri Jun 24, 2011 10:11 am

One thing I ran into, using pptx4j: when I look in an XML version of my PPTX file, I see several Relationships; looks like a 'master' relationship, plus one for every slide, possibly a couple more.

When I try to access these from the code, I retrieved a Relationships object, but when I dug into it, it just gave me the 'master' ("/_rels/.rels") relationship. I wasn't able to get to the slide relationships. Am I doing something wrong, or is this a hole?

Thanks,
Jim

You should see whatever relationships are actually specified in the pptx.

Try running your pptx through the PartsList sample: org.docx4j.samples.PartsList

/_rels/.rels should contain target /ppt/presentation.xml;
This MainPresentation part's rels should in turn contain a rel targetting each slide.

Code: Select all: Part /_rels/.rels Part /ppt/presentation.xml Part /ppt/slides/slide1.xml

Please point at what I'm misunderstanding. I ran PartsList against my pptx file, below, and received the output at bottom. I searched for _rels, and only got one hit, none for the parts such as /ppt/slides/_rels/slide3.xml.rels. Is there something different about my pptx?

My pptx (the top snippet, in XML format):

No, your pptx is fine.

Try (current SVN):

Code: Select all: presentationMLPackage.getMainPresentationPart().getRelationshipsPart()

or with 2.6.0, looking through:

Code: Select all: presentationMLPackage.getParts().getParts()

(though note that that contains all parts except relationship parts)

Or more generally, see the src for PartsList. The rels parts are implicit in the output indentation; they aren't shown, because they'd clutter up the output for little gain.
