ufXtract - Microformats Parser (Beta 0.2.2)

ufXtract is a new microformats parser. It has been built from the ground up to take configurationobjects which allow the parsing of different microformats or POSH patterns. The component alsocontains an extendable output format option.

I am building a test suite to fine tune the components compliancy. Most of the compoundmicroformats apart hCard have some issues at the moment. If you have any comments or want topoint out issues please email - info.backnetwork.com

Example urls

http://lab.backnetwork.com/examples/1/page1.htm

Updated

29-Nov-07Added support for pages encoded with ISO-8859-1.

24-Nov-07Some internal changes which fix given-name in hcards and incorrect Url paths from page whichhave been redirected using 302

16-Nov-07I have added error handling and number of other small improvements such as the reporting feature.The major fixes are that the component will now successfully handle multiple header includes oftenused in hCalendar. The hAtom output has been addressed, but as yet not fully tested.
