Say I've got a directory full of html pages. Their headers and footers are basically the same, but I want to be able to see only the portions of all the pages that are the same. I'd like to call it an n-way merge, but that isn't what it is, it's looking for just the similarities between the header and the footers of all the files.

(and my header I don't mean just the <head> tag, but rather the portions of the page that are alike).

Note: There are like 20 html files.

Is there a name for a tool that does this?
