I modified the code to do this:
Element root = doc.getRootElement();
Iterator elementIterator = root.elementIterator();
while(elementIterator.hasNext()){
Element element = (Element)elementIterator.next();
String name = element.attributeValue("name");
System.out.println(name);
if(!dict.containsKey(name)){
System.out.println(name + " is an extra element...");
root.remove(element);
//element.detach();
System.out.println("Deleted");
}
}
But I still get the same error. Any ideas? Thanks, Ray

Hi Ray, Use remove() on the iterator The message is correct. You are modifying the collection while the iterator is operating. CME is thrown if any modification is make to the collection other than through the iterator

Hello, I am trying to remove nodes on a large set of data:
while(elementIterator.hasNext()){
Element element = (Element)elementIterator.next();
String name = element.attributeValue("name");
System.out.println(name);
if(!dict.containsKey(name)){
System.out.println(name + " is an extra
element...");
element.detach();
}
}
I am getting this error:
java.util.ConcurrentModificationException

I am using dom4j 1.4. Thanks! Ray
