When editing HTML in emacs, is there a way to automatically pretty-format a blob of markup, changing something like this:

    You can pipe a region to xmllint (if you have it) using:
    


    M-|
Shell command on region: xmllint --format -

    


    The result will end up in a new buffer.
    


    I do this with XML, and it works, though I believe xmllint needs certain other options to work with HTML or other not-perfect XML.  nxml-mode will tell you if you have a well-formed document.
