Soap Response: XmlStreamReader Method Help Syntax

After a succesful SOAP request. I am now trying to extract the <SagittaCode> value from the response body below. I am trying to use the XmlStreamReader method getAttributeValue, but not haveing much luck. 

I am getting an error of " Illegal State: Current state is not among the states START_ELEMENT , ATTRIBUTEvalid for getAttributeValue()". 

Thanks for the help!

You would use the getAttributeValue method if you were trying to parse XML content similar to: 
<someObject SagittaCode="string" />
Where SagittaCode would be an attribute within the XML tag. Since you want the content between the starting & ending SagittaCode tags you would do something like: 
String theSagittaCodeValue; //this will the variable that will hold your string
HTTPResponse externalResponse = http.send(externalRequest); //the response from the request
String bodyXML = externalResponse.getBody(); //grab the body of the response
XmlStreamReader reader = new XmlStreamReader(bodyXML); //construct an XmlStreamReader object
while(reader.hasNext()) { //while there are more XML events
	if (reader.getEventType() == XmlTag.START_ELEMENT) { //if this is the opening tag
		if ('SagittaCode' == reader.getLocalName()) { //if the tag is sagittacode
			while(reader.hasNext()) { //while there are more XML events
				if (reader.getEventType() == XmlTag.END_ELEMENT) { //if this is the closing tag
					break; //exist the loop
				} else if (reader.getEventType() == XmlTag.CHARACTERS) { //if this is the content between the tags
					theSagittaCodeValue = reader.getText(); //grab the content
				}
				reader.next(); //advance to the next XML event
			}
		}
	}
	reader.next(); //advance to the next XML event
}


Hope this helps.

This worked. It appears when I look in the logs it is looping through the entire repsonse body before breaking even if it finds the Sagitta code. I will take a look and see if I can get it to break once the value is caputured. Thanks Greg!!
