XmlPullParserException while parsing string.xml file

I am trying to parse an xml file which is similar to string.xml file under res folder. But while parsing I am getting exception. Below is my xml file.

<!-- Enrollment Messages -->
<string name="configure_email_text">No corporate email accounts have been configured on this device. To    configure them, click <b>Configure Email</b></string>
<string name="invalid_credentials">Authentication failed. Enter valid credentials.</string>
<string name="invalid_passcode">Authentication failed. Enter valid Passcode.</string>

And below is my code which I am using to parse XML.

 private void loadXML()
    {
        // TODO Auto-generated method stub
        InputStream ins = null;
        try{
            //Debug.startMethodTracing("parsingdetail");

            ins=getAssets().open("strings.xml");
            XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
            // factory.setNamespaceAware(true);
            XmlPullParser xpp = factory.newPullParser();
            xpp.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, false);
            xpp.setInput(ins, null);
            parseXml(xpp);
            int j=hMap.size();
            if(j>0){
               System.out.println("Anuj Kumar Jha "+j);
            }
        }catch(XmlPullParserException e){
            System.out.println("anuj kumar jha"+e);
            e.printStackTrace();
        }catch(IOException e){
            System.out.println("anuj kumar jha"+e);
            e.printStackTrace();
        }
        finally{
            if(ins!=null){
                try {
                    ins.close();
                }
                catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        }

    }


    private void parseXml(XmlPullParser parser) throws XmlPullParserException,IOException
    {
        // TODO Auto-generated method stub
        int eventType=parser.getEventType();
        while(eventType!=XmlPullParser.END_TAG){
            String key=null;
            String value=null;
            switch(eventType){
            case XmlPullParser.START_TAG:
                String name=parser.getName();
                if(name.equalsIgnoreCase("string")){
                    key=parser.getAttributeValue(null,"name");
                    value=parser.nextText();
                    hMap.put(key, value);
                    if(parser.getEventType()!=XmlPullParser.END_TAG){
                        parser.nextTag();
                    }
                }
            }
            eventType=parser.next();
        }
    }

And Below is the Exception I am getting .

01-18 12:19:10.506: I/System.out(16115): anuj kumar jhaorg.xmlpull.v1.XmlPullParserException: END_TAG expected (position:START_TAG @5:137 in java.io.InputStreamReader@42b54168)

I think it is because of tag in first string tag. How to fix this issue.?
