I haven't done that before, and it seems to have worked ok... Depends whether you want strings or not. $book->name is a SimpleXMLElement object, so if you want the string value it needs to be cast to a string. This will be implicitly done if you use the variable where PHP would expect a string, but in the name of defensive programming I always cast XML values to the type I expect/want them to be. Remove the casts in that snippet and run it - you'll see the variables are not strings.

Ah, thanks for that information. I guess I have just been lucky so far. I will update my code and my style there to make it more accurate and defensible.
