我尝试使用android
解析XMLPullParser
中的XML数据,但我无法解析它。
以下是我的XML数据的一部分。任何人都可以帮我解析这个XML。
任何帮助都会被欣赏。

以下是我用于解析的代码:
public void parse(String liveCADData) throws XmlPullParserException,
IOException {
InputStream in = null;
try {
in = new ByteArrayInputStream(liveCADData.getBytes());
InputStream in1 = in;
BOMInputStream bin = new BOMInputStream(in1, false,
ByteOrderMark.UTF_8);
InputStreamReader in2 = new InputStreamReader(bin);
XmlPullParser parser = Xml.newPullParser();
parser.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, false);
parser.setInput(in2);
parser.nextTag();
readItems(parser);
} finally {
in.close();
}
}
private void readItems(XmlPullParser parser) throws XmlPullParserException,
IOException {
parser.require(XmlPullParser.START_TAG, ns, "live");
while (parser.next() != XmlPullParser.END_TAG) {
if (parser.getEventType() != XmlPullParser.END_TAG) {
continue;
}
String name = parser.getName();
if (name.equals("tt1")) {
String val = readStringValue(parser, "tt1");
}
}
}
private String readStringValue(XmlPullParser parser, String tag)
throws IOException, XmlPullParserException {
parser.require(XmlPullParser.START_TAG, ns, tag);
String stringValue = readText(parser);
parser.require(XmlPullParser.END_TAG, ns, tag);
return stringValue;
}
答案 0 :(得分:1)
标记tt1
没有价值。标签的名称为tt1
。
考虑以下
<active_flag>A</active_flag>
active_flag
是代码名称,值为A
这是你出错的地方
private String readStringValue(XmlPullParser parser, String tag)
throws IOException, XmlPullParserException {
parser.require(XmlPullParser.START_TAG, ns, tag);
String stringValue = readText(parser); // no value for tt1
parser.require(XmlPullParser.END_TAG, ns, tag);
return stringValue;
}
我只展示了如何从特定标签中获取值。样本应足以自己解析其余部分。要解析
public class XMLPullParserHandler {
private String text;
public XMLPullParserHandler() {
}
public Void parse(InputStream is) {
XmlPullParserFactory factory = null;
XmlPullParser parser = null;
try {
factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(true);
parser = factory.newPullParser();
parser.setInput(is, null);
boolean check =false;
//factory instantiates an object
int eventType = parser.getEventType();
while (eventType != XmlPullParser.END_DOCUMENT) {
String tagname = parser.getName();
switch (eventType) {
case XmlPullParser.START_TAG:
break;
case XmlPullParser.TEXT:
text = parser.getText();
break;
case XmlPullParser.END_TAG:
String val = null;
if (tagname.equalsIgnoreCase("active_flag")) {
Log.i("Flag is",text);
}
if (tagname.equalsIgnoreCase("cr_st_1")) {
Log.i("cr_st_1 is",text);
}
if (tagname.equalsIgnoreCase("cr_st_2")) {
Log.i("cr_st_2 is",text);
}
break;
default:
break;
}
eventType = parser.next();
}
} catch (XmlPullParserException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
这是日志
08-20 12:53:09.155: I/Flag is(11804): A
08-20 12:53:09.160: I/cr_st_1 is(11804): SYMONDS
08-20 12:53:09.160: I/cr_st_2 is(11804): ORLANDO
我希望您可以根据上面的示例
