What is the best way in Java to parse semantic data from a source?

I would like to read and parse a marked up text (probably microformat, microdata, rdf or similar). Do I have crea开发者_运维百科te my own parser or is there any java library which can help with this?

Have you already googled from this?! :-) "microformat +java parser" on Google will give you a link to http://microformats.org/wiki/parsers
