Question on Sentence Diagramming

If it possible to diagram the following sentence:

What we have not done is to pass bill after bill after bill that was obviously unconstitutional just so we could all get on record one more time as casting another vote realizing that what was going to happen was someone would file suit the next day and the legislation would never take effect.

can this also be diagrammed?

Never imagine yourself not to be otherwise than what it might appear to others that what you were or might have been was not otherwise than what you had been would have appeared to them to be otherwise.

Can the Text Encoding Initiativehandle either? (The Text Encoding Initiative appears to be the closest approximation to an attempt to diagram sentences, etc. using xml.)
