Accessing XML Using Java Technologies

The most important benefit of XML is its simplicity. While it is simple, is powerful enough to express complex data structures. Java is one of the most important programming language that is used to create your Web pages.

It is an object oriented language whose main objective was to be used with embedded systems such as cell phones. But later it gained more importance for use in Web pages that are dynamic in nature. Java Applet and servelets are important mechanisms for the implementation this.

Another advantage of using Java is the concept of JavaBeans, which is a model of components of Java software, which allows the rapid development of an application, using a visual is a buider.DOM the methods to access the structure of an XML document.

An alternative is to use an event driven API.SAX is a simple API designed to XML.DocumentHandler is very important since it is required each time an item is found. A DocumentHandler is used as follows:

Step 1: Importing the parser interface

Step 2: Create an instance of SAX driver.

Step 3: Using this driver, create a parser object

Step 4: Sign up as an example of a class MyHandler is a set DocumentHandler .

JOX of Java libraries that allows it to transfer data between XML documents and JavaBeans. JOX games XML document for the fields of a bean and he will use a DTD to write a paper when XML is a available.JOX, unlike the other libraries, allows you to use any form of an XML document and without creating any JavaBean separate scheme to describe the mapping between Java and XML.

XP is an XML parser written in Java. The following are the advantages of XP: *

XP is designed to be 100% conformant and correct

* XP aims High performance

* In addition to the high level API parser, which also offers a low level API which supports the construction of different types of parser .

Breeze XML Binder is the most complete Java / XML binding solution available. Brisa creates JavaBeans created directly from the XML structures.
