Question

I just learn how to working with ListView and parsing XML data in Java following this tutorial. However, I’m getting an error because the XML data contains some special characters. Could someone kindly advice me on this issue?

This is my XML Data looks like.

<menu>

<item>      
    <id>1</id>
    <question>What's my phone number?</question>
    <answer>my phone number is "000-000-0000".</answer>        
</item>  

<item>      
    <id>2</id>
    <question>What's my fax number?</question>
    <answer>my fax number is "000-000-0000"</answer>        
</item>  

<item>      
    <id>3</id>
    <question>What's my mailing address?</question>
    <answer>my address here</answer>        
</item> 

<item>      
    <id>4</id>
    <question>What's my web address?</question>
    <answer>https://mywebsite.com/Login/Login.aspx?cID=53044&lng=en-US</answer>        
</item> 

</menu>

And here is the Java class.

public class FaqsQuestionsActivity extends ListActivity {


    static final String URL = "http://myweb.com/faq_list.xml";
    // XML node keys
    static final String KEY_ITEM = "item"; // parent node   
    static final String KEY_ID = "id";
    static final String KEY_QUESTION = "question";
    static final String KEY_ANSWER = "answer";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.faqs_questions);

        ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String, String>>();

        XMLParser parser = new XMLParser();
        String xml = parser.getXmlFromUrl(URL); // getting XML
        Document doc = parser.getDomElement(xml); // getting DOM element

        NodeList nl = doc.getElementsByTagName(KEY_ITEM);

        for (int i = 0; i < nl.getLength(); i++) {

            HashMap<String, String> map = new HashMap<String, String>();
            Element e = (Element) nl.item(i);

            map.put(KEY_ID, parser.getValue(e, KEY_ID));
            map.put(KEY_QUESTION, parser.getValue(e, KEY_QUESTION ));
            map.put(KEY_ANSWER, parser.getValue(e, KEY_ANSWER));

            menuItems.add(map);
        }

        ListAdapter adapter = new SimpleAdapter(this, menuItems, R.layout.faqs_question_list,
        new String[] { KEY_QUESTION, KEY_ANSWER  }, new int[] {R.id.question, R.id.answer});


        setListAdapter(adapter);

        ListView lv = getListView();

        lv.setOnItemClickListener(new OnItemClickListener() {

            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {


                String question = ((TextView) view.findViewById(R.id.question)).getText().toString();
                String answer = ((TextView) view.findViewById(R.id.answer)).getText().toString();


                Intent in = new Intent(getApplicationContext(), FaqsAnswersActivity.class);

                in.putExtra(KEY_QUESTION, question);
                in.putExtra(KEY_ANSWER, answer);
                startActivity(in);

            }
        });
    }
}

You can try to encode your XML before trying to parse it:

String encodedXML = URLEncoder.encode(xml);

And then parse.
