This is a collection of generic functions
for which one can write methods
so that they are called in repsonse to
different SAX events.
The idea is that one defines methods for different
classes of the .state argument
and dispatch to different methods based on that
argument.
The functions represent the different SAX events.
startElement.SAX(name, atts, .state = NULL)
endElement.SAX(name, .state = NULL)
comment.SAX(content, .state = NULL)
processingInstruction.SAX(target, content, .state = NULL)
text.SAX(content, .state = NULL)
entityDeclaration.SAX(name, base, sysId, publicId, notationName, .state = NULL)
.InitSAXMethods(where = "package:XML")the name of the XML element or entity being declared
named character vector of XML attributes
the value/string in the processing instruction or comment
the target of the processing instruction, e.g. the R in
<?R....>
x
the system identifier for this entity
the public identifier for the entity
name of the notation specification
the state object on which the user-defined methods should dispatch.
the package in which the class and method definitions should be defined. This is almost always unspecified.
Each method should return the (potentially modified) state value.
