Here is the code I have to read a XML file:
import org.jdom.*;
import org.jdom.input.SAXBuilder;
import java.io.IOException;
import java.util.*;
public class FibRead {
public static void main(
String[] args) {
if (args.length == 0) {
System.out.println("Usage:
java FibRead URL");
return;
}
SAXBuilder builder = new SAXBuilder();
try {
Document
doc = builder.build(args[0]);
listNodes(doc, 0);
}
// indicates a well-formedness error
catch (JDOMException e) {
System.out.println(args[0] + " is not well-formed.");
System.out.println(e.getMessage());
}
//catch (IOException e) {
// System.out.println(e);
//}
}
public static void listNodes(Object o, int depth) {
printSpaces(depth);
if (o instanceof Element) {
Element element = (Element) o;
System.out.println("Element: " + element.getName());
List children = element.getContent();
Iterator iterator = children.iterator();
while (iterator.hasNext()) {
Object child = iterator.next();
listNodes(child, depth+1);
}
}
else if (o instanceof Document) {
System.out.println("Document");
Document doc = (Document) o;
List children = doc.getContent();
Iterator iterator = children.iterator();
while (iterator.hasNext()) {
Object child = iterator.next();
listNodes(child, depth+1);
}
}
else if (o instanceof Comment) {
System.out.println("Comment");
}
else if (o instanceof CDATA) {
System.out.println("CDATA section");
// CDATA is a subclass of Text so this
test must come
// before the test for Text.
}
else if (o instanceof Text) {
System.out.println("Text");
}
else if (o instanceof EntityRef) {
System.out.println("Entity reference");
}
else if (o instanceof ProcessingInstruction) {
System.out.println("Processing Instruction");
}
else { // This really shouldn't happen
System.out.println("Unexpected type: " + o.getClass());
}
}
private static void printSpaces(int n) {
for (int i = 0; i < n; i++) {
System.out.print(' ');
}
}
}
It works well except in the listnodes function, I would like it to print out the values of the objects, Text, Comment, CData. Currently it only print the elements
