Comment 49 for bug 350407

The issue that I have with working through the DOM is that, currently, anything modified by Firefox before being saved is "corrected". If the page had html like <a href=http://www.google.com>google.com</a>, the address is now enclosed in quotes. Although this is perfectly acceptable for those simply trying to save a page for later, it is not acceptable for web-developers, who would prefer that nothing was changed in their code before being saved. This is why I prefer the, albeit less effective, method of using regular expressions. The URLs can be easily collected through the DOM interfaces (see code in extension mentioned in comment 47 for example). However replacing only those URLs that need to be replaced is difficult, as a regular expression cannot ever beat a full parser for shear flexibility.
