为什么我在下面给出的代码中得到 SAXException。XML 文件处理程序和 logcat 如下所示。处理程序是否有任何问题。这个错误是因为下面显示的 XML。

代码：

try {
            HttpClient client = new DefaultHttpClient();
            HttpGet method= new HttpGet();
            method.setURI(new URI(AppConstatnt.OPCODE_URL+code));

            HttpResponse response=client.execute(method);           
            HttpEntity entity=response.getEntity();         
            InputStream stream=entity.getContent();

            Log.e("b4 execute in login","aditya");

            SAXParserFactory spf = SAXParserFactory.newInstance(); 
            SAXParser sp = spf.newSAXParser(); 
            XMLReader xr = sp.getXMLReader(); 
            OPCodeHandler myopcodeHandler = new OPCodeHandler();
            xr.setContentHandler(myopcodeHandler); 

            xr.parse(new InputSource(stream)); 
            objsitelist = myopcodeHandler.getSiteList();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IllegalStateException e) {
            e.printStackTrace();
        } catch (URISyntaxException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (ParserConfigurationException e) {
            e.printStackTrace();
        } catch (SAXException e) {
            e.printStackTrace();
        }

处理程序：

public class OPCodeHandler extends DefaultHandler {

    boolean currentElement = false;
    String currentValue = "";
    SitesList siteobject;

    public SitesList getSiteList() {
        return siteobject;
    }

    public void setSiteList(SitesList objsite) {
        siteobject = objsite;
    }

    @Override
    public void startElement(String uri, String localName, String qName,
            Attributes attributes) throws SAXException {
        currentElement = true;
        currentValue = "";
        if (localName.equalsIgnoreCase("opcode")) {
            siteobject = new SitesList();
        }
    }

    @Override
    public void characters(char[] ch, int start, int length)
            throws SAXException {

        if (currentElement) {
            currentValue = new String(ch, start, length);
            currentElement = false;
        }
    }

    @Override
    public void endElement(String uri, String localName, String qName)
            throws SAXException {
        currentElement = false;
        if (localName.equalsIgnoreCase("tsip")) {
            siteobject.setTsip(currentValue);
        }
        if (localName.equalsIgnoreCase("ssip")) {
            siteobject.setSsip(currentValue);
        }
        if (localName.equalsIgnoreCase("brand")) {
            siteobject.setBrand(currentValue);
        }
        if (localName.equalsIgnoreCase("balance")) {
            siteobject.setBalance(currentValue);
        }
        if (localName.equalsIgnoreCase("rates")) {
            siteobject.setRates(currentValue);
        }

        if (localName.equalsIgnoreCase("domain")) {
            siteobject.setDomain(currentValue);
        }
        if (localName.equalsIgnoreCase("operator")) {
            siteobject.setOperator(currentValue);
        }
        if (localName.equalsIgnoreCase("active")) {
            siteobject.setActive(currentValue);
        }
        if (localName.equalsIgnoreCase("opcode")) {
            setSiteList(siteobject);
        }

    }

}
