RSS Component [IP*Works! V8]

Properties Methods Events Configuration Settings

The RSS component is used to retrieve, parse, and write RSS syndicated content.

NOTE: What follows is a very short description of the component interfaces. For more information, please consult the help files that come with the respective package.

Remarks

The RSS component implements a standard RSS newsreader with extended capabilities as specified at http://backend.userland.com/rss2.

The component contains a number of properties that map directly to RSS fields. To receive a feed call the GetFeed method with the URL or file to retrieve specified in the URL parameter. The RSS component can also generate RSS feeds, which can be retrieved through the RSSData property or written through the WriteFile method.

The RSS component supports all RSS feed properties that are standard in versions 0.91, 0.92 and 2.0 of the RSS protocol through a number of component properties. It also supports non-standard properties as specified in the RSS protocol through the Namespaces properties and the GetProperty and SetProperty methods.
