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. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/
