Detailed Description

TBParser subclass that uses a SAX parser in the XERCES library.

Synopsis

TBXercesSAXParser is a subclass of TBParser that implements all the parsing methods using a XERCES SAX parser. If XML parsing is required, the TBXercesSAXParser is recommended for its (relative) speed. TBXercesSAXParser also implements xerces::DefaultHandler since SAX uses event-driven parsing.
