This seems to be doing exactly what you want. It’s just your code with some typos fixed.

        var reportXML:XML =              <Report>                 <prop1>4</prop1>                  <prop2>2255</prop2>                  <prop3>true</prop3>                  <prop4>false</prop4>                  <prop5>true</prop5>              </Report>;          var myArray:Array = [{xmlNodeName: 'prop5', value: false}];          for each (var item:Object in myArray)         {             reportXML[item.xmlNodeName] = item.value.toString();         }          trace(reportXML);
