class TSAXParser: public TXMLParser


TSAXParser

TSAXParser is a subclass of TXMLParser, it is a wraper class to
libxml library.

SAX (Simple API for XML) is an event based interface, which doesn't
maintain the DOM tree in memory, in other words, it's much more
efficient for large document.

TSAXParserCallback contains a number of callback routines to the
parser in a xmlSAXHandler structure. The parser will then parse the
document and call the appropriate callback when certain conditions
occur.

Function documentation

TSAXParser()
 Create SAX parser.
~TSAXParser()
 TSAXParser desctructor
void OnStartDocument()
 Emit a signal for OnStartDocument.
void OnEndDocument()
 Emit a signal for OnEndDocument.
void OnStartElement(const char* name, const TList* attr)
 Emit a signal for OnStarElement, where name is the Element's name and
 attribute is a TList of (TObjString*, TObjString *) TPair's.
 The TPair's key is the attribute's name and value is the attribute's
 value.
void OnEndElement(const char* name)
Emit a signal for OnEndElement, where name is the Element's name.
void OnCharacters(const char* characters)
 Emit a signal for OnCharacters, where characters are the characters
 outside of tags.
void OnComment(const char* text)
 Emit a signal for OnComment, where text is the comment.
void OnWarning(const char* text)
 Emit a signal for OnWarning, where text is the warning.
Int_t OnError(const char* text)
 Emit a signal for OnError, where text is the error and it returns the
 Parse Error Code, see TXMLParser.
Int_t OnFatalError(const char* text)
 Emit a signal for OnFactalError, where text is the error and it
 returns the Parse Error Code, see TXMLParser.
void OnCdataBlock(const char* text, Int_t len)
 Emit a signal for OnCdataBlock.
Int_t Parse()
 This function parses the xml file, by initializing the parser and checks
 whether the parse context is created or not, it will check as well
 whether the document is well formated.
 It returns the parse error code, see TXMLParser.
Int_t ParseFile(const char* filename)
 It creates the parse context of the xml file, where the xml file name is
 filename. If context is created sucessfully, it will call Parse()
 It returns parse error code, see TXMLParser.
Int_t ParseBuffer(const char* contents, Int_t len)
 It parse the contents, instead of a file.
 It will return error if is attempted to parse a second file while
 a parse is in progres.
 It returns parse code error, see TXMLParser.
void ConnectToHandler(const char* handlerName, void* handler)
 A default TSAXParser to a user-defined Handler connection function.
 This function makes connection between various function from TSAXParser
 with the user-define SAX Handler, whose functions has to be exactly the
 same as in TSAXParser.

 handlerName is the user-defined SAX Handler class name
 handler is the pointer to the user-defined SAX Handler

 See SAXHandler.C tutorial.
