scrubyt

I've written a scrubyt extractor based on the 'learning' technique - that is, specifying the current text on the page and getting it to work out the XPath expressions itself. However, I now want to export the extractor so that it can be used even when the page has changed.

The documentation for scrubyt seems to be all over the place now, but from what I can find I should be able to put the line extractor.export(__FILE__) and it should work. It doesn't - I just get an error saying that there is the wrong number of arguments for export, it should have 0. I've tried it without any arguments and it still fails.

I would ask on the scrubyt forum, but it seems like no-one's been there for ages!

Any ideas what to do here?
