Note: this returns a tree, not an element. Use ``parse(...).getroot()`` to get the document root. If ``guess_charset`` is true, the ``useChardet`` option is passed into html5lib to enable character detection. This option is on by default when parsing from URLs, off by default when parsing from file(-like) objects (which tend to return Unicode more often than not), and on by default when parsing from a file path (which is read in binary mode).
