In particular, XMLPULL has two major flaws: These are two very big problems.With respect to XML, XMLPULL does not support namespaces by default and does not read or report well-formedness errors in the internal DTD subset.The trade-offs made in the name of size may be acceptable if you're working in J2ME.They are completely unacceptable in a desktop or server environment.However, these APIs model the parser rather the document. Unresolvable entities cause an Technically this is invalid XHTML, but it is not malformed.They push the content of the document to the client application as soon as they see it, whether the client is ready to receive that data or not. You can turn on validation for documents by passing true to the factory's set Validating() method before instantiating the parser.However, because the existing XMLPULL parsers don't support validation, robustness requires adding a lot of validation code to the program that would not be necessary in the SAX or DOM equivalent.This is probably only worthwhile when the DOM equivalent program would use too much memory.
You can pass null for either the namespace or the element name to indicate that all namespaces and/or names are acceptable.However, it is best to test and verify your expectations about data formats. Pull parsers don't yet support validation, but XMLPULL offers an alternative.If you expect a particular token to be present in the document, you can require it using a type and an optional name and namespace.However, as the name indicates, it is based on a pull model rather than a push model. This simple example doesn't demonstrate the full power of the XMLPULL API.In XMLPULL the client is in control rather than the parser. Since the client application controls the process, it's easy to write separate methods for different elements.
