[jdom-interest] delete element from xml file

[Deepa Janamatti (RBEI/EMT2)]

Hello,

Using an Iterator might lead to ConcurrentModificationException. So, use ListIterator instead of Iterator to remove the element.

Regards,
Deepa

Hi,

You should not iterate on children and modify the content directly on the 
element at the same time.
In your for() loop, use i.remove() to remove the current element.
