No need to even do that. The document is the same document (zero copy
which is why going back and forth is efficient), so when its changed by
the xinclude call, it is reflected in $xml already. Only reason you
would need to do conversions back and forth is if you need specific
nodes that might have been added/changed by the other extension. Here
you are using the same root element and dont have to worry about losing
any child references you might already have, so its a wasted call.
So really when you perform:
$dom = dom_import_simplexml($xml);
the $dom object is really created by taking a reference to the $xml
object rather than copying it? i.e. (I know this isn't real code)
$dom = dom_import_simplexml(& $xml);
Is this correct?
