Strip citations from text

I realize this is a rather niche request, but I figured why not put it out there in the spirit of open source. I read a lot of documents with many case and statutory citations that are basically useless in speed-reader form. I suspect people in academia would have a similar issue. I would like to suggest an option to strip citations from the text as part of the parsing process. I tried to track down some regular expressions that match typical citation forms and came up with these:

http://stackoverflow.com/questions/7054764/regular-expression-for-legal-citation
http://pyparsing.wikispaces.com/share/view/10397114

The pyparsing example appears to be a good starting place but would need to be implemented in JS. Alternatively, maybe someone out there has already solved this precise problem (but I couldn't find it).

Another lower tech option would be to have an option to strip text matching any arbitrary number of patterns in the configuration interface--this would save the user from having to tangle with the source code.
