This function is EXPERIMENTAL. The behaviour of this function, the name of this
function, and anything else documented about this function may change in a future release of PHP
without notice. Be warned and use this function at your own risk.

domxml_root() takes one argument, an object of class "Dom document", and returns
the root element node. There are actually other possible nodes like comments which are currently
disregarded.
The following example returns just the element with name CHAPTER and prints it. The other
root node -- the comment -- is not returned.
