How to get the page's full content as string in javascript?
<p>I'm  writing a bookmarklet, i.e. a bookmark that contains javascript instead of a URL, and I have some trouble. In fact, I cannot remember how I can get the content of the page as a string, so I can apply a regular expression to find what I want. Can you please help me on this?</p>

<p>Before anyone suggests it, I cannot use getElementBy(Id/Name/Tag), because the data I'm looking for is HTML-commented and inside  markups, so I don't think that would work.</p>

<p>Thanks.</p>
