RE: removing element from document

Just change the inside of the loop from:

                      //throws ConcurrentModificationException
                      feature.getChild("FIELDS").removeContent(field);

to:

                      //throws ConcurrentModificationException
                      j.remove();

It is 'well-documented' that if you have an integrator, you can't change
the collection apon which the iterator is based, unless you use the
iterator to make the change. See the ConcurrentModificationException
javadoc.

Subject: [jdom-interest] removing element from document

Hello All,

I need to remove all the Elements from a Document who have a particular
attribute w/ a particular value.  My first (unsuccessful) attempt was
Element#removeContent w/in an iterator loop which throws a
ConcurrentModificationException.

Can someone suggest to me the correct way to do this sort of thing?

Thanks!

          List features =
root.getChild("RESPONSE").getChild("FEATURES").getChildren("FEATURE");
          for (Iterator i=features.iterator();i.hasNext();) {
              feature = (Element) i.next();
              fields = feature.getChild("FIELDS").getChildren("FIELD");
              for (Iterator j=fields.iterator(); j.hasNext();) {
                  field = (Element)j.next();
                  if ("#SHAPE#".equals(field.getAttributeValue("name")))
{
                      //throws ConcurrentModificationException
                      feature.getChild("FIELDS").removeContent(field);
                  }
              }            
          }
