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.cCs@tj|_tj|_tj|_tj|_dS(N( thandlertContentHandlert _cont_handlert DTDHandlert _dtd_handlertEntityResolvert _ent_handlert ErrorHandlert _err_handler(tself((s)/usr/lib64/python2.7/xml/sax/xmlreader.pyt__init__scCstddS(sAParse an XML document from a system identifier or an InputSource.s This method must be implemented!N(tNotImplementedError(R tsource((s)/usr/lib64/python2.7/xml/sax/xmlreader.pytparsescCs|jS(s#Returns the current ContentHandler.(R(R ((s)/usr/lib64/python2.7/xml/sax/xmlreader.pytgetContentHandler"scCs ||_dS(s:Registers a new object to receive document content events.N(R(R R((s)/usr/lib64/python2.7/xml/sax/xmlreader.pytsetContentHandler&scCs|jS(s Returns the current DTD handler.(R(R ((s)/usr/lib64/python2.7/xml/sax/xmlreader.pyt getDTDHandler*scCs ||_dS(s7Register an object to receive basic DTD-related events.N(R(R R((s)/usr/lib64/python2.7/xml/sax/xmlreader.pyt setDTDHandler.scCs|jS(s#Returns the current EntityResolver.(R (R ((s)/usr/lib64/python2.7/xml/sax/xmlreader.pytgetEntityResolver2scCs ||_dS(s0Register an object to resolve external entities.N(R (R tresolver((s)/usr/lib64/python2.7/xml/sax/xmlreader.pytsetEntityResolver6scCs|jS(s!Returns the current ErrorHandler.(R (R ((s)/usr/lib64/python2.7/xml/sax/xmlreader.pytgetErrorHandler:scCs ||_dS(s3Register an object to receive error-message events.N(R (R R((s)/usr/lib64/python2.7/xml/sax/xmlreader.pytsetErrorHandler>scCstddS(sHAllow an application to set the locale for errors and warnings.

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.iicCs||_tj|dS(N(t_bufsizeRR (R tbufsize((s)/usr/lib64/python2.7/xml/sax/xmlreader.pyR os cCsddl}|j|}|j||j}|j|j}x/|dkrw|j||j|j}qIW|jdS(Nit(tsaxutilstprepare_input_sourcet prepareParsert getByteStreamtreadR'tfeedtclose(R RR*tfiletbuffer((s)/usr/lib64/python2.7/xml/sax/xmlreader.pyRss    cCstddS(sThis method gives the raw XML data in the data parameter to the parser and makes it parse the data, emitting the corresponding events.
