UfXtract is a fast and easy to use .Net microformats parser. With a few lines of code you can load and parse microformats from Urls or HTML strings. You can then extract the data directly in .Net or convert it into JSON, JSON-P or XML.
UfXtract currently supports the following microformats hCard, hCalendar, hReview, hResume, hAtom, XFN, rel-tag, geo, adr, rel-nofollow, rel-license, rel-directory, rel-home, rel-enclosure, rel-payment and votelinks.It also supports a handful of POSH patterns hCard-XFN, rel-me, rel-next/previous, test-suite and test-fixture. The support of rel-me and rel-next/previous was added to help people build social graph spiders.
UfXtract can typically parse a page between 10-50ms. I have gone to some pains to build a test suite to make sure it conforms as closely as possible to the microformats specs.
You can also easily create new microformats and POSH definitions using some simple .Net objects.
UfXtract is an open source project. Please help by contributing to documentation, reporting bugs, forking the code to add features or make bug fixes etc
