I don't know any tool but I know there is a simple way to do this:

• First, use a regular expression tool to strip off all the text in your HTML file. You can use this regular expression to search for the text (?<=^|>)[^><]+?(?=<|$) and replace them with an empty string (""), i.e. delete all the text. After this step, you will have all HTML markup tags. There are a lot of free regular expression tools out there.
• Then, you repeat the first step for the original HTML file.
• Last, you use a diff tool to compare the two sets of HTML markups. This will show what is missing between one set and the other.
