(There's also XPropertyLog, by which xmobar reads an arbitrary X
property, and PipeReader, which reads from a given pipe.)

By reading the _NET_ACTIVE_WINDOW X atom (which is set by the window
manager), one can obtain the id of the currently active window.  From
there, one can get its title.

Unfortunately, i just checked xmonad and, unlike sawfish or openbox, it
doesn't seem to set it. We would need to provide a code snippet that
sets that property explicitly.
