While working with XML documents, you need to validate the documents. You may use setValidating() method on a SAX or DOM factory. But Java 5.0 (JAXP 1.3) introduces JAXP validation framework which can also be used for validating XML documents.
Using the JAXP validation framework is fairly simple and efficient. In JAXP 1.3, the validation is broken out into several classes within the new javax.xml.validation package. Lets go through the steps:
1. Load the model in to
To change the parser implementations, JAXP provides a class called SAXParserFactory. I will present an example that will show how to use this class.
First thing is to create an instance of SAXParserFactory. After creating the new instance, we have to get he SAX-capable parser. For thos, factory provides a method. Good thing is that the JAXP implementation takes care of the vendor-dependent code and thus keeps the code clean. This factory has some other nice features, as well. Do explore
If you want to process XML data using applications written in the Java programming language, then JAXP is the best choice. JAXP stands for Java API for XML Processing. I will introduce JAXP in this post.
JAXP can be called an abstraction layer since it does not introduces any new way to parse XML documents nor it provides different way of handling XML documents. Actually it makes using DOM and SAX easier. Using JAXP, you may habdle vendor-specific tasks that may arise when dealing
