Seeking a multi- commented code can successfully resolve this xml grateful

------ Solution ------------------- -------------------------
own pull parser can read ah, read attributes starttag in ah.
------ eference --------------------------------------- < br> Thank you, but the problem is I want to read the content ( "success" ) is a node inside the property , which is how to read ?
------ eference ------------------------------------ ---
you this "success " is a property, so there are two ways to get attribute names and values:
getAttributeName ()
getAttributeValue ()
case XmlPullParser.START_TAG:
. . .
if (xmlParser.getAttributeCount () == 1) {
String attrValue = xmlParser.getAttributeValue (0) ;/ value / get is "success"
}

String result = " " ;
int eventType = parser.getEventType ();
while (eventType! = parser.END_DOCUMENT) {
if (eventType == parser.START_TAG) {
String tagName = parser.getName ();
if (tagName.equls ("PDAExchange")) {
result = parser.getAttributeValue ("returnMsg");
}
}
eventType = parser.next ();
}
Log.i ("result", result);

still did not parse it out I'm going crazy ! ! !
Where should I change ? To put some xml parsing out ?
server returns some XML:
something
/ / This result is mounted above this XML
System.err.println (" XML to parse is :" + result);
InputStream inStream = new ByteArrayInputStream (result.getBytes ());
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance ();
/ / get a DocumentBuilder parsing class
DocumentBuilder builder = factory.newDocumentBuilder ();
/ / receives an xml string to parse xml, Document representatives entire xml document
Document document = builder.parse (inStream);
/ / get the root element node xml document
Element personsElement = document.getDocumentElement ();
/ / get NodeList tagged PDAExchange collection of Node objects
NodeList nodeList = personsElement.getElementsByTagName ("string");
for (int i = 0; i
/ / If the Node is an Element
if (nodeList.item (i). getNodeType () == Document.ELEMENT_NODE)
{
Element personElement = ; (Element) nodeList.item (i);
/ / Node get the property values of
String Nodname = ; personElement.getAttribute ("returnMsg");
System.err.println ( Nodname);
NodeList childNodesList = ; personElement.getChildNodes ();
for (int j = 0; j
if (childNodesList.item (j). getNodeType () == Document.ELEMENT_NODE)
{
/ / resolves to a person below the name tag
if ("Vid". equals (childNodesList.item (j). getNodeName ()))
{
/ / get the name tag text value
String name = childNodesList.item (j) getFirstChild () getNodeValue ()..;
System.out.println (name);
}
else if ("Authority". equals (childNodesList.item (j). getNodeName ()))
{
String age = childNodesList.item (j) getFirstChild () getNodeValue ()..;
System.out.println (age);
}
}
}
}
}

you this "success " is a property, so there are two ways to get attribute names and values:

case XmlPullParser.START_TAG:
. . .
if (xmlParser.getAttributeCount () == 1) {
String attrValue = xmlParser.getAttributeValue (0) ;/ value / get is "success"
} should help us to see how to write
Where is the problem ? server returns some XML:

generally help you debug it, your problem lies in one place : personsElement.getElementsByTagName (" string ");
Here there should be "string", but " PDAExchange ".
DocumentBuilderFactory factory = null;
DocumentBuilder builder = null;
Document document = null;
InputStream inputStream = null;
factory = DocumentBuilderFactory.newInstance();
try {
//inputStream = this.getResources().getAssets().open("info.xml");
inputStream = new ByteArrayInputStream(result.getBytes());
//log("inputStream : " + inputStream);
factory = DocumentBuilderFactory.newInstance();
// 得到一个DocumentBuilder解析类
builder = factory.newDocumentBuilder();
// 接收一个xml的字符串来解析xml,Document代表整个xml文档
document = builder.parse(inputStream);
// 得到xml文档的根元素节点
Element personsElement = document.getDocumentElement();
// 得到标签为PDAExchange的Node对象的集合NodeList
NodeList nodeList = personsElement.getElementsByTagName("PDAExchange");
log("length : " + nodeList.getLength());
for (int i = 0; i < nodeList.getLength(); i++) {
// 如果该Node是一个Element
if (nodeList.item(i).getNodeType() == Document.ELEMENT_NODE) {
Element personElement = (Element) nodeList.item(i);
// 得到Node的属性值
String Nodname = personElement.getAttribute("returnMsg");
log(Nodname);
NodeList childNodesList = personElement.getChildNodes();
for (int j = 0; j < childNodesList.getLength(); j++) {
if (childNodesList.item(j).getNodeType() == Document.ELEMENT_NODE) {
// 解析到了person下面的name标签
if ("Vid".equals(childNodesList.item(j).getNodeName())) {
// 得到name标签的文本值
String name = childNodesList.item(j).getFirstChild().getNodeValue();
log(name);
} else if ("Authority".equals(childNodesList.item(j).getNodeName())) {
String age = childNodesList.item(j).getFirstChild().getNodeValue();
log(age);
}
}
}
}
}
} catch (IOException e) {
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
} catch (SAXException e) {
e.printStackTrace();
} catch (ParserConfigurationException e) {
e.printStackTrace();
} finally {
try {
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
Good luck !

thank you very much for your patience directly compiled a good code said he was grateful to me ; Figure 2 first I put the server returns XML print out System.err.println (" XML to parse is :" + result);
Then if parsing is successful :
/ / get the property value of Node
String Nodname = ; personElement.getAttribute ("returnMsg");
System.err.print ( Nodname);
if ("Vid". equals (childNodesList.item (j). getNodeName ())) {
/ / get the name tag text value
String name = childNodesList.item (j) getFirstChild () getNodeValue ()..;

red circle to see your notes say " there are no red circle thing" if getLength () is 0 , then , is it your InputStream problem ?
resolved because on my computer all the time has a value , the code just like you, is not the same InputStream
