You can use TreeWalker in the Sun XML lib to access a node by its
name. If you want to traverse the DOM tree, you have to handle the white
space. Try to implement a recursive method and print out all the child
nodes with its value, take a look at IBM XML4J example.

For your case,
try
Node sibling = root.getFirstChild();
sibling = sibling.getNextSibling();

System.out.println((sibling=sibling.getNextSibling.getFirstChild()).getNodeValue());

You should be able to see "Roses are red,"
now.
