Answer 1

Second argument of SimpleXMLElement::addChild is only used for string values, like:

<first_name>Oliver</first_name>

If you have subelements in the element, you have to create them without specifying a string value (a subelement created will be returned by addChild ), and then populate with attributes, values, and sub-elements of their own.
