Java & XML Parsing XML Response String

[Ed Berrey]

Error is: java.net.MalformedURLException: no protocol: <?xml version="1.0"?>

Code used is:
try {
factory = SAXParserFactory.newInstance();
saxParser = factory.newSAXParser();
} catch (Exception e) {
System.out.println("In ShipmentTrackingAction.execute - " + e);
}
try {
handler = new DefaultHandler() {
boolean Shipment_ = false;
public void startElement(String uri, String localName, String qName, Attributes attributes)
throws SAXException {
if (qName.equalsIgnoreCase("Shipment")) {
Shipment_ = true;
}
}

public void characters(char ch[], int start, int length) throws SAXException {
if (Shipment_) {
System.out.println("Shipment: ");
parsedResponse.append("Shipment: ");
parsedResponse.append("<br>");
Shipment_ = false;
}
}
};
saxParser.parse(dhlResponse, handler);
} catch (Exception e) {
parsedResponse.append(dhlResponse);
System.out.println("In ShipmentTrackingAction.dhlParser - " + e);
e.printStackTrace();
}
//return parsedResponse.toString();
return parsedResponse.toString();
}


XML trying to parse starts like this:
<?xml version="1.0"?>
<ECommerce version="1.1" action="Response" timestamp="2005/08/18T12:35:54" transmission_reference="E14D4E8C">

As dhlResponse is a string (I'm assuming, since you are appending it to parsedResponse which I guess is a StringBuffer), then you are invoking the parse method on SAXParser with the signature:

void parse(String uri, DefaultHandler dh)

from the JavaDoc for SAXParser

As you can see, the first parameter is a URI, not an XML string. So the parser is trying to open your XML string as a URI, and thus the exception.
You will need to use an InputSource as the first parameter of the parse method.

Use a ByteArrayInputStream to get your String into InputSource format.

Thank you very much.
Was exactly what was needed.
Code now works as designed.
Again, thank you!
