JiBX is a framework for binding XML data to Java objects. It lets you work with data from XML documents using your own class structures.

rtfx converts RTF files into a generic XML format. It focuses on keeping metadata such as style names rather than every bit of formatting. This makes it handy for converting RTF documents into a custom XML format (using XSL or an additional processing step). It used to be called 'rtfm', but was changed due to a naming conflict.
