You also set a factory attribute to specify the parser language to use.(For SAX parsing, on the other hand, you set a property on the parser generated by the factory).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.Again, the schemas can be declared either as part of the XML data set or in the program. In general, though, it is a good idea to keep all the declarations together in one place.) To declare the schemas to use for the preceding example in the data set, the XML code would look something like the following.declaration consists of entry pairs, where the first entry in each pair is a fully qualified URI that specifies the namespace, and the second entry contains a full path or a relative path to the schema definition. In that way, only one copy of the schema will tend to exist.
XML DTDs enable the specification of: An XML DTD is not itself written in XML, but is a context-independent grammar for defining the structure of an XML document.
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.
