Seems to work for me now?

Wow! I'm very impressed. Minor issue: The page number doesn't seem to get filled in correctly, and for many journals (like Physical Review Letters), page number is crucial for identifying the article. For instance, I pasted

Hmm. Took me a while to figure out how to work the online demonstration. It needs to be formatted as XML like the examples. Unfortunately, when I inserted some references from a paper I currently am reading (like "R. Delbourgo and J. R. Fox, J. Phys. A 10, L233 (1977)."), it mistakes the journal "J. Phys. A" (i.e., "Journal of Physics A") for a person's name. In contrast, copy-pasting this into Google Scholar returns the correct result.

Thanks Mvolz. I agree that parsing a formatted citation into a citation template is complicated, but I think there may already be "off the shelf" solutions for this (Zotero?). And obviously, this work flow works and could be automated (with scraping, I guess): (1) past formatted citation in Google Scholar; (2) click "cite" button and choose bibtex formatting; (3) convert citation in bibtex format to citation in wiki format.

This issue must have been raised before, but I could not find it after significant searching on Phabricator. Apologies if so.
