Calls to the delegate will happen on the same thread where the parser runs.

This is a low-level streaming XML parser, a thin wrapper for libxml2's SAX parser. It doesn't do much Foundation-ifying quite on purpose -- because the goal is performance and low memory use.

This class is not meant to be sub-classed. Use the delegate methods.
