How do i extract the data from that xml object which is a value of a certain array:
Array ( [Title] => SimpleXMLElement Object (
[0] => The Key of Life; A Metaphysical Investigation )
[ASIN] => SimpleXMLElement Object ( [0] => 0982385099 ) ...
Do string typecasting of the object.
$variable = (string) $FieldValue[0];
That would work, as SimpleXml has all the children in object type and not string.
