Origimi 0.3: Extractors

Hi, I just tagged the code for Origami as 0.3 (https://github.com/xokomola/origami) In this 'release' I added Extractors. With these you can build node extraction functions from composable selectors. This still doesn't make Origimi a full templating library but it's starting to be useful, for example, for screen-scraping HTML as I will show in an upcoming blog post. I did have to let go of BaseX 7.9 compatibility which means it now only runs on recent snapshots (I tested on yesterday's snapshot). It may work on older snapshots but I do not know which. Welcome to the cutting edge ;-) Happy to receive comments and improvements. --Marc
