Virtual Devices


A basic RSS reader that retrieves content from the URL specified at its input. The configuration tag accepts a single URL for now. The device has 8 outputs: TITLE, LINK, DESCRIPTION, SOURCE, ENCLOSURE, AUTHOR, DATE and CATEGORY corresponding to the RSS 2.0 elements of the ITEM tag. The incorporated XPath processor extracts data from the RSS stream and generates an array of strings for each output. Initially, each output port contains the first element of each array. A NEXT command applied to the CTRL port advances to the next element in each array. Currently only RSS 2.0 streams are handled properly. The next version will support additional RSS versions.
