This request is mainly related to Feedburner and their "feedburner:origLink* property.
I’ve tested different tricks to try and extract it but I could only grab 1 item from the list or the entire list is returned as 1 item
I’m considering writing a simple php script to do this conversion for me but I was wondering if it’d be something worth including in the RSS Feed Read node
Another alternative would be to create a node that can set/increment/decrement integers and be referenced in a Function node using Javascript
Side note:
I’m a long time user of Zennoposter which has a similar concept for creating and automating workflows and browser emulation. It’s worth checking out for ideas on what nodes to add
