Eclipse hangs when working with XML's ..
the default editor is too slow and gives lot problem

回答1:
You can customize them: Window -> Preferences -> General -> Editors -> File Associations
There, you'll have to either select a file extension,
or add one to the list and choose what editor eclipse should use
to open it with whenever it's needed.
回答2:
To just open the file once,
Right Click - Open With
To change association,
Windows - Preferences - General - Editors - File Associations
