It's not clear for which call you get the Fatal Error. Check each call to a DOMXML
method like:
if(!object->method()){
print("ERROR in calling method()");
}
The DOMXML methods return either a valid object or FALSE in case of error. Also I'd
suggest setting error_reporting(E_ALL); at the begining of your script when doing
development.
An intermmediate check would be if $f_child->child_nodes() returns an array
(is_array()).
FINALLY: check for spelling mistakes in your variable names; It sounds stupid but I
spent 1 hour once because I was just getting the "call to a member function on a
non-object...".
