一部の Web サービス xml データを取得しましたが、一部のタグは などのタグで構成され<br><p>ているため、データを処理できません。正規表現を使用して特殊文字を削除する方法を知ることはできますか?また、実行時に説明が UI に出力されない理由を誰かに教えてもらえますか? データを取得するための私のコードは次のとおりです。

static final String URL = "http://api.eventful.com/rest/events/search?app_key=42t54cX7RbrDFczc&location=singapore";
    // XML node keys

    static final String KEY_DESC = "description";

    String description = KEY_DESC.replaceAll("<.*?/>", "");

for (int i = 0; i < nl.getLength(); i++) {
            // creating new HashMap
            HashMap<String, String> map = new HashMap<String, String>();
            Element e = (Element) nl.item(i);
            map.put(description, "Description: " + parser.getValue(e, description));            
            // adding HashList to ArrayList
            menuItems.add(map);

        }
ListAdapter adapter = new SimpleAdapter(this, menuItems,
                R.layout.list_item, new String[] {description}, new int[] {R.id.description});

String description1 = ((TextView) view
                        .findViewById(R.id.description)).getText().toString();

                // Starting new intent
                Intent in = new Intent(getApplicationContext(),
                        SingleMenuItemActivity.class);
                in.putExtra(KEY_TITLE, title);
                in.putExtra(KEY_DESC, description1);

                startActivity(in);

特殊文字の説明の例を次に示します。

これは編集されたコードです：

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        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_EVENT);
        // looping through all item nodes <item>
        for (int i = 0; i < nl.getLength(); i++) {
            // creating new HashMap
            HashMap<String, String> map = new HashMap<String, String>();
            Element e = (Element) nl.item(i);
            // adding each child node to HashMap key => value
            map.put(KEY_TITLE, parser.getValue(e, KEY_TITLE));
            map.put(KEY_URL, parser.getValue(e, KEY_URL));
            map.put(KEY_DESC, "Description: " + parser.getValue(e, KEY_DESC));
            map.put(KEY_START_TIME, parser.getValue(e, KEY_START_TIME));
            map.put(KEY_STOP_TIME, parser.getValue(e, KEY_STOP_TIME));
            map.put(KEY_VENUE_NAME, parser.getValue(e, KEY_VENUE_NAME));
            map.put(KEY_COUNTRY_NAME, parser.getValue(e, KEY_COUNTRY_NAME));
            // adding HashList to ArrayList
            KEY_DESC.replaceAll("\n","").replaceAll("</{0,1}.+?>", "");

            menuItems.add(map);

</{0,1}.+?>必要に応じて代わりにこの正規表現を使用してください。ここで私の例<.*?/>を見ることができます

\nそして、最初のようにそのテキスト内のすべてを削除するのが最善です:

someStrings.replaceAll("\n", " ").replaceAll("</{0,1}.+>", "");

私の理解が正しければ、生成している XML で HTML タグがエラーを引き起こしていることが問題です。この答えはそれを助けるでしょう: AndroidでXMLをエンコードする方法は?

山かっこを削除しようとしているだけの場合は、おそらく正規表現なしで簡単に削除できます。最悪の場合、文字列の文字をループして、どれが '<' または '>' であるかをテストし、それらを変更または削除することもできます。
