[jdom-interest] Iterating through XML

[Patrick Simon]

Hi Edd,

when starting with JDOM I had kind of the same (understanding)issue:
think of the *getChildren*() Method. It can do the job.

Here's a proposal snippet how I would  do it
(this is my first  'helping-out-submittal' - To the pros on this list:
please correct me (don't beat me) if accidently I am saying sthg 
wrong...;-))


// start with some root element...
Element oEleRoot = doc.getRootElement();

// get down to Response element
Element oEleResponse = oEleRoot.getChild("Response");

// get all children called  InboundMessage
List oListInBoundMsg = oEleResponse.getChildren("InboundMessage");
      
 // create Iterator
Iterator oIterator = oListInBoundMsg.iterator();
       
Element oEleTicket;
Element oEleMessageText;
Element oElePhone;
Element oEleDate;

//Loop:
while (oIterator.hasNext()) {
                    
//derive Reference from current iterator
Element oEleNext = (Element) oIterator.next();

oEleTicket = oEleNext.getChild("Ticket");
oEleMessageText = oEleNext.getChild("MessageText");
//...more Elements

// call method to do sthg with the Elements data
strStatus=furtherProcessElements(oEleTicket, oEleMessageText /*...*/);

// or even:
// strStatus=processInBoundMsg(oEleNext);

// requires some Status+error handling but not to forget...
// if anything goes wrong: LEAVE THE LOOP
if (!(strStatus.equals(strOK))) {
   break;
}

}// while...


hope this is of help to you...
