If you'd simply like to make sure you're contents are in the right contents etc. etc. you can create a simple testing suite that's going to be making GET requests to your website. When you receive all the content you can run it through a validation template like xslt. Well formed html will usually be able to be matched against xslt's or xsd's. It is not ideal but if you're only worried about the structure of your website and not the styling you'll be able to achieve it this way.
