the longest run of parsed character data. This method may return
before markup due to reaching the end of the input buffer or any
other reason.

structure are not guaranteed to remain valid upon subsequent calls
to the entity scanner. Therefore, the caller is responsible for
immediately using the returned character data or making a copy of
the character data.
