[XML-DEV Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] SAX2 Event Sequence [Was: Re: SAX2: relative ordering of startDocument()
[As promised sometime ago, a summary of the SAX2 event sequence.] Mixing all possible events in from ContentHandler, DTDHandler, LexicalHandler, and DeclHandler, the legal event sequence appears to be: SAXDocument := startDocument (processingInstruction | comment)* DTDEvents? (processingInstruction | comment)* ElementEvents? (processingInstruction | comment)* endDocument DTDEvents := startDTD DTDContent* endDTD DTDContent := startEntity DTDContent* endEntity | elementDecl | attributeDecl | notationDecl | internalEntityDecl | externalEntityDecl | unparsedEntityDecl | skippedEntity | (processingInstruction | comment)* ElementEvents := startPrefixMapping* startElement ElementContent* endElement endPrefixMapping* # Note: "startPrefixMapping" # and "endprefixMapping" events # are balanced (by prefix name) # (and are nested?). ElementContent := ElementEvents | startEntity ElementEvents* endEntity | characters | ignorableWhitespace | startCDATA characters* endCDATA | skippedEntity | (processingInstruction | comment)* [terminals (which start with [a-z]) represent SAX2 events; non-terminals (starting with [A-Z]) added for structuring purposes.] For a more complete & possibly prettier document, see: http://www.mds.rmit.edu.au/~msf/misc/SAXEvents.html which includes the above, plus a brief description of each event and the SAX2 class to which the actual method belongs.
