Validating parser xml
If the schema definition does not define a target namespace, then it applies to the default (unnamed, or null) namespace.So, in our example, you would expect to see these target namespace declarations in the schemas: An array of Objects can be used only when the schema language has the ability to assemble a schema at runtime.Let's start with one of the most basic facts about using parsers: Unless you happen to be developing XML-processing software, you can pretty much forget about this question. But it's not really a question to concern yourself with if you're just interested in browsing XML, editing it, or creating style sheets.It's like asking, "I want to buy a car and I want to make sure the wheels will stay on. The developer of the browsing application will almost certainly have made the decision for you, and you can probably override it only with difficulty (and perhaps intellectual pain).To be notified of validation errors in an XML document, the following must be true: It is helpful to start by defining the constants you will use when configuring the factory.
Note - The material discussed in this section also applies to validating when using the SAX parser.
This month, however, we tackle just one, the question of questions -- the question that nearly everyone asks at some point: Which XML parser should I use?
