You can write a NodeJS script using the JSDom module to do this.

Thanks for the suggestion. Any idea how to accomplish this task without using JS?

I'm surprised chromium, konqueror and firefox don't offer this functionality for offline browsing.

Selenium (http://seleniumhq.org/) might work but it's not a simple command line script.

Selenium will do this, although it's not pretty. I spent about 4 months on a contract doing exactly that, and it sucked.
