Class DOMEcho

java.lang.Object

xml.DOMEcho

public class DOMEcho
extends Object

Program to echo a DOM tree using DOM Level 2 interfaces. Use JAXP to read in and create a DOM tree. DOM currently does not provide a method to do this. (This is planned for Level 3.) See the method main for the three basic steps. Once the application obtains a DOM Document tree, it dumps out the nodes in the tree and associated node attributes for each node. Notes: Program flags may be used to create possibly non-conformant (but useful) DOM trees. Program also shows an example of using an ErrorHandler.
