これは、Google API からの出力です。Androidアプリで解析しようとしています。私はそれを解析するためにDOMを使用しています。次のコードがあります。

    Document doc = null;
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    try {

        DocumentBuilder db = dbf.newDocumentBuilder();

        InputSource is = new InputSource();
        is.setCharacterStream(new StringReader(xml));
        doc = db.parse(is);

    } 

    Element root = doc.getDocumentElement();

    NodeList nl = doc.getElementsByTagName("CompleteSuggestion");

    for (int i = 0; i < nl.getLength(); i++) {
        Element suggestion = (Element)nl.item(i);
        String name = suggestion.getAttribute("suggestion");
        System.out.println(name);
    }

正しい属性値を取得できません。毎回空になります。

どうも！ラフル。

提案は要素の属性ではなく、データは要素提案の属性です。これを使って：

for (int i = 0; i < nl.getLength(); i++) {
        Element c_suggestion = (Element)nl.item(i);
        Element suggestion = c_suggestion.getElementsByTagName("Suggestion")
        String name = suggestion.getAttribute("data");
        System.out.println(name);
    }
