SimpleXMLElement::asXML — Return a well-formed XML string based on SimpleXML element
The asXML method formats the parent object's data in XML version 1.0.
If specified, the function writes the data to the file rather than returning it.
If the filename isn't specified, this function returns a string on success and FALSE on error. If the parameter is specified, it returns TRUE if the file was written successfully and FALSE otherwise.
