Hi
I'm sorry, but I don't understand well what you are trying to tell me.....
Let's imagine I want to modify an existent XML file called customers.xml
I should do this steps
$doc = new DOMDocument();
$doc->load('customers.xml');
$root = $doc->getElementsByTagName("customers"); // to take the root
.... // create one customer
$doc->save('customer.xml'); // to save the changes
that is exactly what I did in the else part (in the if, in the case the file customers.xml didn't exist, I create the file with only the root node).
Isn't is right?
For what concerns the two type of DOMDocument istantiation.... I forgot to chance them both :)
Thks

It looks to me that you are creating a new DOM object for the file
existing condition, but not loading the actual file into the object with
$doc->load() or similar. Consequently you are creating a new file with
single entry each time.
Also, I wonder why your new DOMDocument()s have different parameters?
Wouldn't it be wise to make them the same to avoid possible problems?
