Recursive OPML Data

While it isn’t commonly used, the OPML spec allows for recursive data – that is, folders with folders within folders. However, until Version 2.0.0 of MT-Outliner, you couldn’t get at this data easily – at least not for displaying it on your Movable Type-powered blog.

Now I’ve added an MTOutlinerRecurse tag to MT-Outliner. I put together a page with the details on how it works, but at least for me, the subject is difficult to grasp when reading about it – but it does work! Try playing with the tag to see how it can add additional dimensions to your OPML output. You will, of course, need to have these multiple levels in your OPML files!

Many thanks to David Raynes, not only for starting me down the recursion path with his SubCategories plugin, but for responding to my email asking for help!
