我使用以下代码来解析XML,它已经从官方的Android Docs中引用:
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(true);
XmlPullParser xpp = factory.newPullParser();
xpp.setInput(new StringReader(response));
int eventType = xpp.getEventType();
while (eventType != XmlPullParser.END_DOCUMENT) {
if (eventType == XmlPullParser.START_DOCUMENT) {
System.out.println("Start document");
} else if (eventType == XmlPullParser.START_TAG) {
System.out.println("Start tag " + xpp.getName());
} else if (eventType == XmlPullParser.END_TAG) {
System.out.println("End tag " + xpp.getName());
} else if (eventType == XmlPullParser.TEXT) {
// System.out.println("Text " + xpp.getText());
}
eventType = xpp.next();
}
System.out.println("End document");
在控制台上:
06-08 11:13:25.557 24857-24883/ex.com.receipts I/System.out﹕ Start document
06-08 11:13:25.557 24857-24883/ex.com.receipts I/System.out﹕ Start tag exareceipts
06-08 11:13:25.557 24857-24883/ex.com.receipts I/System.out﹕ Start tag email
06-08 11:13:25.557 24857-24883/ex.com.receipts I/System.out﹕ End tag email
06-08 11:13:25.557 24857-24883/ex.com.receipts I/System.out﹕ Start tag authentication_status
06-08 11:13:25.557 24857-24883/ex.com.receipts I/System.out﹕ End tag authentication_status
06-08 11:13:25.557 24857-24883/ex.com.receipts I/System.out﹕ End tag exareceipts
06-08 11:13:25.557 24857-24883/ex.com.receipts I/System.out﹕ End document
但是我只对名为authentication_status
的节点感兴趣,我知道我需要检查:
if(xpp.getName().equalsIgnoreCase("authentication_status")){
//logic for getting node value
}
我真的很困惑和不确定 - 在哪里放置此代码。

好的,这是怎么做的:
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(true);
XmlPullParser xpp = factory.newPullParser();
String tagName = null;
xpp.setInput(new StringReader(response));
int eventType = xpp.getEventType();
while (eventType != XmlPullParser.END_DOCUMENT) {
if (eventType == XmlPullParser.START_DOCUMENT) {
System.out.println("Start document");
} else if (eventType == XmlPullParser.START_TAG) {
System.out.println("Start tag " + xpp.getName());
tagName = xpp.getName();
} else if (eventType == XmlPullParser.END_TAG) {
System.out.println("End tag " + xpp.getName());
} else if (eventType == XmlPullParser.TEXT) {
if(tagName.equalsIgnoreCase("authentication_status")){
System.out.println("Text tagName " + xpp.getText());
}
}
eventType = xpp.next();
}
System.out.println("End document");
