Instances of IncrementalParser offer the following additional
methods:
feed(
data)
Process a chunk of data.
close(
)
Assume the end of the document. That will check well-formedness
conditions that can be checked only at the end, invoke handlers, and
may clean up resources allocated during parsing.
reset(
)
This method is called after close has been called to reset the
parser so that it is ready to parse new documents. The results of
calling parse or feed after close without calling reset are
undefined.
