This example uses the Loop module to combine elements of an XML data stream to create the title element for an RSS feed. By assigning the output of a String Builder sub-module to a new element (in this case title) we can add elements to the data stream.
Our input data is from a government emergency warning system in California. It's plain old XML, not RSS, but with a little help, we can convert it. The String Builder sub-module combines two elements, headline and severity, to create our new title.
We select the "assign results to" option and type in "title". We also have the option to select an existing data element from the list box.
After the Loop, we pass the data through a Rename module, where we convert the expires field into a pubDate field expected for RSS. Luckily, a description field already existed in the input data, so no other conversion is needed.
