What I'm looking for is a way to quickly grep/parse through every post I have ever made. The parse should be on the raw HTML/markup text, and not what is seen in the WYSIWYG editor.

I know the content of wordpress posts/pages are stored in a database and not in text files on your hosting server. If there is a simple SQL querry I can do to extract all the raw text from the database, that would suffice as well.

Again, I don't want to CHANGE anything, just extact a copy. I also don't necessarily want to extract the HTML files of every post/page, but JUST the content of "post_content" for each post/page (aka, what you see in the editor when clicking from "Visual" to "Text").

Thanks.
