Create a Dataset from an HTTP XML Feed
Using the HTTP (XML Feed) dataset type, you can create data models from RSS and XML feeds over the Web by retrieving data through the HTTP GET method.
To include parameters for the dataset, it's recommended that you define the parameters first, so that they're available for selection when you define the dataset. See Add Parameters and Lists of Values.
There's no metadata available from HTTP XML feed datasets, therefore grouping and linking aren't supported.
You might require additional configuration to access external data source feeds depending on your system's security. For example, if the RSS feed is protected by Secure Sockets Layer (SSL).
