There is no way to reliably determine which is being used. This is a
design flaw in those formats that explicitly allow for such embedding
which alas affects those that don't allow it, since the "technique" is
used with all of them.

About the best you can do is assume that anything that "looks like" HTML
is HTML, since you will then have the correct results more often than
not with the data that's out there.
