XMLReader is the interface that an XML parser's SAX2 driver must
implement. This interface allows an application to set and query
features and properties in the parser, to register event handlers
for document processing, and to initiate a document parse.
All SAX interfaces are assumed to be synchronous: the parse
methods must not return until parsing is complete, and readers
must wait for an event-handler callback to return before reporting
the next event.c C s, t j� | _t j� | _t j� | _t j� | _d S )N) r ZContentHandler�

� Zdd� Z dS )�IncrementalParseras This interface adds three extra methods to the XMLReader
interface that allow XML parsers to support incremental
parsing. Support for this interface is optional, since not all
underlying XML parsers support this functionality.
When the parser is instantiated it is ready to begin accepting
data from the feed method immediately. After parsing has been
finished with a call to close the reset method must be called to
make the parser ready to accept new data, either from feed or
using the parse method.
Note that these methods must _not_ be called during parsing, that
is, after parse has been called and before it returns.
By default, the class also implements the parse method of the XMLReader
interface using the feed, close and reset methods of the
IncrementalParser interface as a convenience to SAX 2.0 driver
writers.� � c C s || _ tj| � d S )N)�_bufsizer r

passed to the parser through the feed method, to notify the

do the final checks on the document and empty the internal
data buffer.

the reset method has been called.

read entities.
This class may include information about the public identifier,
system identifier, byte stream (possibly with character encoding
information) and/or the character stream of an entity.
Applications will create objects of this class for use in the
XMLReader.parse method and for returning from
EntityResolver.resolveEntity.
An InputSource belongs to the application, the XMLReader is not
allowed to modify InputSource objects passed to it from the
application, although it may make copies and modify those.Nc C s" || _ d | _d | _d | _d | _d S )N)�_InputSource__system_id�_InputSource__public_id�_InputSource__encoding�_InputSource__bytefile�_InputSource__charfile)r
