First, before you go any further, do you understand that you do NOT have
XML, but rather have the default dynamic object hirearchy? Flex
converts your xml into this structure by default.
Unless you have a conscious reason to use this default, you should set
resultFormat="e4x" on your HTTPService. Then tweak your handler (per
caffeinewabbit's suggestion ) like so:
private var _xmlResult:XML; //instance data model var
...
protected function defaultResult(event:ResultEvent):void
{
_xmlResult = XML(event.result);
trace(xmlResult.toXMLString()); //to see what you have
if(result.errorCode > 0)
Alert.show([EMAIL PROTECTED]); //assuming errorText is an
attribute.
}
}//
To consume the data, bind to the _xmlResult var:
...text="{_xmlResult.MyNode.MyOtherNode.text()}"

HTTPService?
Thank you... would you also have an example on how i can reuse
defaultResult on a loop so each XML node name would bind to a field?
hope that makes sense
