[jdom-interest] Removing Elements

[Rolf Lear]

Hi Bashiro.

Chris is right, doing a remove() changes the size(), so you are skipping 
items....

Iteration is your friend, but there is no need to go backwards... are 
you using JDOM 2.0.0?

Element root = document.getRootElement();
Iterator<Element> it = root.getChildren().iterator();
while (it.hasNext()) {
     Element emt = it.next();
     if (ID.equals(emt.getAttributeValue("contacts"))) {
         it.remove();
     }
}


Otherwise:

Element root = document.getRootElement();
Iterator it = root.getChildren().iterator();
while (it.hasNext()) {
     Element emt = (Element)it.next();
     if (ID.equals(emt.getAttributeValue("contacts"))) {
         it.remove();
     }
}
