</mc:AlternateContent>

It contains rPr and mc:AlternateContent. My problem here is that when I try to do r.getContent(), you would expect to have two elements rPr and mc:AlternateContent. But in actual result, you would only have pict, since the behavior goes like: r.getContent() only fetches elements inside the <mc:Fallback> tag.

What I want to have is, I want to retrieve <a:graphic> which is definitely inside <mc:Choice>.<w:drawing>.<wp:anchor>.

Answer 1

In general, the presence of an mc element causes an UnmarshalException, since it is invalid content according to the schemas used in docx4j.

When that happens, docx4j pre-processes the content through org/docx4j/jaxb/mc-preprocessor.xslt which usually selects the mc:Fallback content.

You have various options to override this behaviour:

• easy: you can supply your own xslt, which does something different; see the property "docx4j.jaxb.JaxbValidationEventHandler" to point to its location
• more complex and completely unsupported: alter the XSDs to allow mc namespace content in the element of interest, then regenerate the relevant classes using xsd
• modify a jaxb implementation itself, to cope with how the markup compatibility mechanism works. This would be very cool!

For more, Google 'office openxml markup compatibility and extensibility' or try this TC45 final draft.
