Validating non validating parser xml
Your response in finalizing this old question is appreciated.By now, you have done a lot of experimenting with the nonvalidating parser.Conforming XML processors fall into two classes: validating and non- validating.Non-validating processors are REQUIRED to check only the document entity, including the entire internal DTD subset, for well-formedness.while DOM gave us facility of tree structure which we can obtain from an XML document after parsing it with SAX parser.By default the instance of parser which we obtain by calling SAXParser Factory method new Instance() is non validating but u can make it validating by SAXParser Factor's method set Validating(true).Here, you use the constants you defined earlier to specify the W3C's XML Schema language: In the process, however, there is an extra error to handle. In addition to the error handling you've already learned about, there is one error that can occur when you are configuring the parser for schema-based validation.
So now you know that a DTD is a requirement for a valid document. What happens when you run the parser on your current version of the slide presentation, with the DTD specified? That code is reproduced here: is a validation error, although you have seen that it can also be generated if the file specifies a version of XML that the parser is not prepared to handle.For now, think of these attributes as the "magic incantation" you use to validate a simple XML file that doesn't use them.After you've learned more about namespaces, you'll see how to use XML Schema to validate complex documents that use them.Infact JAXP was developed for some project X (Sun's implementstion).As far as your question about Validating and non Validating is concerned, either we use SAX or DOM we use the same parser which is the SAX's paser.
Sun's implementation supports any combination of configuration options.
