Convert XFDF to FDF

QUICK ANSWER
Is it possible to convert XFDF to FDF?
Yes - XFDF converts to FDF.

Adobe Acrobat can export form data as FDF instead of XFDF (Tools > Prepare Form > More > Export Data). FDF and XFDF carry the same data in different syntaxes (binary PDF-like vs XML). iText/PDFBox can convert between the two programmatically.
