PHP SoapClient - send xml string

I need to post xml content from a string using PHP SoapClient It looks like SoapClient accepts arrays only, like this $soapClient->method(array()); Here is a sample xml file to be used ?xml version="1.0" encoding="utf-16"?> <Data xmlns:xsd="[login to view URL]" xmlns:xsi="[login to view URL]"> <master>myn</master > <state>VA</state> <info> <item> <name>ID</name> <value>00000011111111</value> </item > < item > <name>FullName</name> <value>test full name</value> </item > < item > <name>Phone</name> <value>101011010101</value> </item > </info> </Data> I need a php script sending the xml string via soapClient.
