Question

当我尝试使用XML Pull解析器解析xml文件时，我收到异常。异常说XmlPullParserException：意外的令牌（位置：java.io.stringreader@40e06970中的TEXT @ 1：2）请给我一个解决方案，我的代码是，

Answer 1

国家/地区列表标记未结束

</CountriesList>

你可以在这里验证xml

http://www.xmlvalidation.com/

试试这个xml

<CountriesList>

    <countries>

        <country>
Afghanistan
        </country>
    </countries>

    <countries>

        <country>
Albania
        </country>
    </countries>

    <countries>

        <country>
Algeria
        </country>
    </countries>


</CountriesList>

UPDATE这将以logcat

打印国家/地区

public void xmlParse(String file) throws XmlPullParserException, IOException {
        Log.i("String", "going in xml parse");
        boolean demoflag = false;
        Data d = null;

        XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
        factory.setNamespaceAware(true);
        XmlPullParser xpp = factory.newPullParser();

        xpp.setInput(new StringReader(file));
        int eventType = xpp.getEventType();

        while (eventType != XmlPullParser.END_DOCUMENT) {
            Log.i("String", "in while");
            switch (eventType) {
            case XmlPullParser.START_DOCUMENT:
                break;

            case XmlPullParser.START_TAG:
                if (xpp.getName().equalsIgnoreCase("country")) {
                    demoflag = true;
                }
                break;
            case XmlPullParser.TEXT:
                if (demoflag) {
                    Log.i("country", "" + xpp.getText().trim());
                }
                break;
            case XmlPullParser.END_TAG:
                if (xpp.getName().equalsIgnoreCase("country")) {
                    demoflag = false;
                }
                break;
            default:
                break;
            }

            eventType = xpp.next();
        }

    }
