tailieunhanh - XML programming in Java

Our previous tutorial discussed the basics of XML and demonstrated its potential to revolutionize the Web. In this tutorial, we’ll discuss how to use an XML parser to: • Process an XML document • Create an XML document • Manipulate an XML document We’ll also talk about some useful, lesser-known features of XML parsers.
