Format selection
UfXtract currently supports 12 microformats and 5 POSH patterns. Each is defined in a format describer which has to be passed to the parser and sometimes the data convertor.
Currently supported formats
UfXtract 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-payement and votelinks. It also supports a handful of POSH patterns hCard-XFN, rel-me, rel-next/previous, test-suite and test-fixture. The direct support of rel-me, rel-next/previous was added to help people build social graph spiders.
Code example
using UfXtract; string url = ""; string formatString = ""; UfFormatDescriber formatDescriber = null; ; if (Request.QueryString["format"] != null) formatString = Request.QueryString["format"]; if (Request.QueryString["url"] != null) url = Request.QueryString["url"]; switch (formatString) { case "hcard": formatDescriber = UfFormats.HCard(); break; case "hcalendar": formatDescriber = UfFormats.HCalendar(); break; case "hreview": formatDescriber = UfFormats.HReview(); break; case "hresume": formatDescriber = UfFormats.HResume(); break; case "hatom": formatDescriber = UfFormats.HAtomItem(); break; case "xfn": formatDescriber = UfFormats.Xfn(); break; case "tag": formatDescriber = UfFormats.Tag(); break; case "geo": formatDescriber = UfFormats.Geo(); break; case "adr": formatDescriber = UfFormats.Adr(); break; case "no-follow": formatDescriber = UfFormats.NoFollow(); break; case "license": formatDescriber = UfFormats.License(); break; case "votelinks": formatDescriber = UfFormats.VoteLinks(); break; case "hcard-xfn": formatDescriber = UfFormats.HCardXFN(); break; case "me": formatDescriber = UfFormats.Me(); break; case "nextprevious": formatDescriber = UfFormats.NextPrevious(); break; case "test-suite": formatDescriber = UfFormats.TestSuite(); break; case "test-fixture": formatDescriber = UfFormats.TestFixture(); break; } if (formatDescriber != null && url != "") { UfWebRequest webRequest = new UfWebRequest(); webRequest.Load(url, formatDescriber); if (webRequest.Data.Nodes.Count > 0) { UfDataToJson dataConvertor = new UfDataToJson(); Response.ContentType = "application/json"; Response.Write(dataConvertor.Convert(webRequest.Data, formatDescriber)); } }
