BeautifulSoup takes string data fed to it, and builds a structure
that can be neatly navigated. That string data can come from a
web page, from a disk, or even a serial port, a
random-character-generator, or just from HTML that's built up in
memory and never sees a network or a disk. It's worth reading
its documentation and trying its examples to get familiar with it.
