Parsing an XML Document to Display Node Type and Content

In the previous example, the code listed the names of each node in the ch07_01.xml document. However, you can do more than that: You can also use the nodeValue property to list the value of each node, and I'll do that in this section. In addition, you can indicate the type of each node you come across by checking the nodeType property. Here are the possible values for this property:

• 2: Attribute

• 3: Text
