Delphi soap (return array)

I just started to use Delphi,
I don't know how to iterate over arrays.
I already did the connection between Delphi and soap.
I want to get the name (for exemple Arnold ) and to set in a TForm1.Edit1Change
I know how to do when I get a string but I don't know for a array.


in wsdl, I get:
  ArrayOf_xsd_string = TArray<String>;

  customerCtrlPortType = interface(IInvokable)
  ['{3C177C7E-853B-10B9-0F41-CA0B073BBF64}']
    function  ViewCustomer(const id: Integer): ArrayOf_xsd_string; stdcall;
  end;

in PHP, I get:
  Array ( [1] => Array ( [first] => Schwarzenegger [last] => Arnold ) [2] => Array ( [first] => Stallone [last] => Sylvester ) )

in xml, I get:
<item>
      <key xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xsd:int">1</key>
      <value xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:Map">
            <item>
                  <key xsi:type="xsd:string">first</key>
                  <value xsi:type="xsd:string">Schwarzenegger</value>
            </item>

            <item>
                  <key xsi:type="xsd:string">last</key>
                  <value xsi:type="xsd:string">Arnold</value>
            </item>
      </value>
</item>
<item>
      <key xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xsd:int">2</key>
      <value xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:Map">
            <item>
                  <key xsi:type="xsd:string">first</key>
                  <value xsi:type="xsd:string">Stallone</value>
            </item>
            <item>
                  <key xsi:type="xsd:string">last</key>
                  <value xsi:type="xsd:string">Sylvester</value>
            </item>
      </value>
</item>
