Huge amount of plaintext data for parsing experiment

I am developing a parser in ruby which parses some nonunifor开发者_如何学Gom text data. Can anybody tell me, where I can get a good number of plaintext data for that?

You could scrape Wikipedia (or just run a bunch of it through lynx -dump). That would also give you a vast source of non-English text as well. Project Gutenberg would be another good source of large amounts of plain text.
