Parse an XML document.
The parser can use this method to instruct this configuration
to begin parsing an XML document from any valid input source
(a character stream, a byte stream, or a URI).
Parsers may not invoke this method while a parse is in progress.
Once a parse is complete, the parser may then parse another XML
document.
This method is synchronous: it will not return until parsing
has ended. If a client application wants to terminate
parsing early, it should throw an exception.
