I have tried every browser plugin that I could find. I am trying to validate an application. It uses ajax. There are many holder divs that are set with innerHTML. All attempts I have tried only validate the original markup and not the generated content. I purposely put invalid content into the divs dynamically and try to validate and it still validates. How can I validate the dynamic content? I can see that in chrome or with firebug that the content is viewable element by element. Is there a plugin that can look at the generated content and validate it?
