Small problem reading an XML document

Question

Hi,
I have code that can read an XML document like this:
<?xml version="1.0" encoding="UTF-8"?>
<something>
<order orderid="1">
<customerid>12341</customerid>
</order>
</something>
but when I take out the first tag <something> and last tag </something> , it doesn't work at all and I have no clue why. Here is my code:
public class SaveOrders extends Object {
      try {
         //Get the root element and all order elements
         Element ordersRoot = ordersDoc.getDocumentElement();
         NodeList orders = ordersRoot.getElementsByTagName("order");
         for (int i = 0; i < orders.getLength(); i++) {
            //For each order, get the order element
            Element thisOrder = (Element)orders.item(i);
      } catch (ClassNotFoundException e) {
         System.out.println("Error creating class: "+e.getMessage());thanks for your help!

Every XML document must have a Document Root (in your case <something>). So, if you have multiple <order>'s within your XML document, there is no Doc Root! Eeek!
Get it? If you only have one <order> per XML file, then you should be alright (and might have another problem) because that <order> becomes the root, but the instant you have more than one, you need something to put all of them (your Doc Root).
Hope that helps!
