我尝试提取欧洲地区的childNodes的所有'name'属性（<region type="continent" name="europe"...>，但我只得到前5个元素的名称。如果这些国家有childNodes，我也需要提取它们，但我现在的主要目标是国家。名称属性为'finland'的区域本身有childNodes，但是解析器查看名字=“aland”的第一个子节点并完全打破了循环。
public static Region parsedXMLForEurope(String xmlFile) {
List<Region> allRegions = new ArrayList<>();
Region region = new Region("Europe");
try {
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
XmlPullParser parser = factory.newPullParser();
parser.setInput(new StringReader(xmlFile));
int eventType = parser.getEventType();
while(eventType != XmlPullParser.END_DOCUMENT) {
Log.i("XMLParser", "******************");
Log.i("XMLParser", "Current counrtry is: " + parser.getAttributeValue(null, "name"));
switch (eventType) {
case XmlPullParser.START_TAG:
if(parser.getName().equals("region") && parser.getAttributeValue(null, "poly_extract").contains("europe")) {
Log.i("XMLParser", "******************");
Log.i("XMLParser", "Current country is: " + parser.getAttributeValue(null, "name"));
region.pushRegion(new Region(parser.getAttributeValue(null, "name")));

你有没有尝试过：
JSONObject jsonObj = XML.toJSONObject(xmlFile);
JSONArray jsonArray = jsonObj.getJSONObject("region").getJSONArray("region");
JSONObject jsonObjFromJsonArray = jsonArray.toJSONObject(0);
JSONObject jsonArrayObjForCountryRegion = jsonObjFromJsonArray.getJSONObject("region");
然后你可以将它用作JSON对象..访问数据非常容易，而不是解析XML内容。
