XML Parsing

When starting to learn about XML parsing I refered the following link http://java.sun.com/developer/Books/xmljava/ch03.pdf. There I came to know about Apache Xerces parser which is suitable for Java and C applications. The latest version of Apache Xerces is xerces-2_9_1. I have downloaded it from http://xml.apache.org. Simple API for XML(SAX) was also attached with this software. XML document is parsed with this. SAX has collection of classes and interfaces which is helpful in parsing with callbacks. So I tried a small sample program with this . Executed it successfully. I have to learn more in this. And now proceeding furhter examples in the above sun's link.
