    <mx:webservice id="weatherservice" wsdl="http://www.webservicex.com/globalweather.asmx?wsdl"

                   fault="defaultfault(event)">

        <mx:operation name="getweather"

                      fault="showerrordialog(event)"

                      result="log(event)"

                      resultformat="xml">

            <mx:request>

                <cityname>{mycity.text}</cityname>

                <countryname>{mycountry.text}</countryname>

            </mx:request>

        </mx:operation>

    </mx:webservice>

    <mx:textinput id="mycity" text="madrid"/>

    <mx:textinput id="mycountry" text="spain"/>

    <!-- call web service operation button click. -->

    <mx:button width="60" label="get weather"

              click="weatherservice.getweather.send();"/>

    <!-- display weather -->

    <mx:label text="weather:"/>

    <mx:textarea text="{weatherservice.getweather.lastresult}" height="200"/>

</mx:application>

the wsdl says getweatherresponse string, , appears string of xml, set <mx:operation resultformat="object"> unwrap soap response value , leave string typed value intact. can create new actionscript 3.0 e4x-based xml instance unwrapped string:

 

    var myxml:xml = new xml(event.result.tostring());

 

you can travese xml document using e4x syntax, simple example included below:

 

    trace(myxml..location);

    trace(myxml..temperature);
