Validating parser software sax transferability and updating of disaggregate travel demand models
The bulk of the XML processors tested were non-validating ones.For applications where enforcing the rules in a document type declaration is not necessary, a wide variety of choices and design tradeoffs is available.If the text to be output is not in a CDATA section, then any angle brackets, ampersands, and other special characters in the text should be replaced with the appropriate entity reference.(Replacing left angle brackets and ampersands is most important, other characters will be interpreted properly without misleading the parser.) But if the output text is in a CDATA section, then the substitutions should not occur, resulting in text like that in the earlier example.But if a validation error occurs in a document, you probably do not want to continue processing it. To take over error handling, you override the Warnings, too, are ignored by default.
It is not illegal, and it does not cause problems, but it is something you might like to know about because it might not have been intentional.
The code handles that case by using the qualified name whenever the simple name is an empty string.
The JAXP SAX API also allows you to handle the characters that the parser delivers to your application, using the Parsers are not required to return any particular number of characters at one time.
You finish parsing text when an element ends, so you normally perform your character processing at that point.
But you might also want to process text when an element starts.
