Hey, author here. I built this as a weekend project over the last weekends. It's open source and the direct link to the repository is here: https://github.com/dewey/feedbridge
Pretty cool, there's a few services out there that do similar things, but haven't seen a open source version yet. Any plans to create a (visual?) tool to aid with creating a new plugin? Where you could click/select elements and the tool generates XPath/RegEx?
Not yet, but I'll think about it if I get tired of manually implementing plugins.
