Need some help in parsing this XML in J2ME platform

Below mentioned is my XML,

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelopexmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<Response xmlns="http://tempuri.org/">
<Result>
    <mp_response>
        <data signature="something">
                  <outcome errorcode="0" errordescription="" errorsolution=""/>
                 something
</data>
</mp_response>
</Result>
</Response>
</soap:Body>
</soap:Envelope>

I wish to extract the "errorcode" from this XML. How I am suppose to do that ? Please help.

Solution

  • If your target devices support SAX from JSR 172, you should go with this parser. It will reduce your app's final jar size (no libs imported). There is a good sample at http://www.developer.nokia.com/Community/Wiki/JSR_172:_XML_Parsing_Example It actually unmarshalls the XML into Java objects.

    After you feel confident you may try my generic approach to unmarshalling in Java ME at http://smallandadaptive.blogspot.com.br/2010/11/xml-data-binding.html
