我想解析一个xml文件。我试图找到错误，但我找不到它。你能帮我吗，请问？ XML：
<maintag>
<data>
<id>1</id>
<name>x y</name>
<age>16</age>
<phone>06/30 123-4567</phone>
<address>Veszprem Valami ut 10.</address>
</data>
<data>
<id>2</id>
<name>p q</name>
<age>18</age>
<phone>06/70 987-6543</phone>
<address>Budapest Ulloi ut 21.</address>
</data>
</maintag>
XMLParser类：
package com.example.xmlproba;
import java.util.jar.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
import android.util.Log;
public class XMLParser extends DefaultHandler {
boolean xmlStartLine = false;
boolean id = false;
boolean data = false;
boolean maintag = false;
boolean age = false;
boolean name = false;
boolean phone = false;
boolean address = false;
Data currentData;
DataContainer dataContainer;
public XMLParser(DataContainer dataContainer){
this.dataContainer=dataContainer;
Log.d("FUNC","XMLPARSER()");
// Data d = new Data();
}
public void startElement(String uri, String localName, String qName,
Attributes attributes) throws SAXException {
Log.d("START","START");
if (qName.equalsIgnoreCase("MAINTAG")) {
Log.d("Maintagfound","mtf");
} else if (qName.equalsIgnoreCase("DATA")) {
//create new data object
currentData = new Data();
Log.d("NEWDATA","NEWDATA");
} else if (qName.equalsIgnoreCase("ID")) {
id = true;
Log.d("id","id");
} else if (qName.equalsIgnoreCase("NAME")) {
name = true;
Log.d("name","name");
} else if (qName.equalsIgnoreCase("AGE")) {
age = true;
} else if (qName.equalsIgnoreCase("PHONE")) {
phone = true;
} else if (qName.equalsIgnoreCase("ADDRESS")) {
address = true;
} else {
}
}
@Override
public void endElement(String uri, String localName, String qName)
throws SAXException {
Log.d("END","END");
if (qName.equalsIgnoreCase("DATA")) {
//todo at the end of a data node
//dataContainer.addDataToList(currentData);
//dataContainer.dataList.add(currentData);
}
}
@Override
public void characters(char[] ch, int start, int length)
throws SAXException {
Log.d("CHARS","CHARS");
if (id) {
String s = new String(ch, start, length);
currentData.setId(Integer.parseInt(s));
Log.d("IDIDID",s);
id = false;
} else if (name) {
String s = new String(ch, start, length);
Log.d("NAME1",s);
currentData.setName(s);
Log.d("NAME2",currentData.getName());
name = false;
} else if (age) {
String s = new String(ch, start, length);
currentData.setAge(Integer.parseInt(s));
age = false;
} else if (phone) {
String s = new String(ch, start, length);
currentData.setPhone(s);
phone = false;
} else if (address) {
String s = new String(ch, start, length);
currentData.setAdress(s);
address = false;
} else {
}
}
}
我的活动的解析部分：
private void readXML() {
// TODO Auto-generated method stub
Log.d("FUNC","READXML");
try {
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
XMLParser xp = new XMLParser(dataContainer);
xr.setContentHandler(xp);
InputStream is = getResources().openRawResource(
R.raw.data);
xr.parse(new InputSource(is));
} catch (ParserConfigurationException e) {
// TODO Auto-generated catch block
Log.d("PARSERCONFEX","PARSERCONFEX");
e.printStackTrace();
} catch (SAXException e) {
// TODO Auto-generated catch block
Log.d("SAXEX","SAXEX");
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
Log.d("IOEX","IOEX");
e.printStackTrace();
}
}
从log.d（）我可以看到只创建了构造函数的日志，“CHARS”和“END”日志。 这是我的日志：

答案 0 :(得分：0)
这是一个使用SAX想要做的事情的例子
数据
public class Data {
private Integer id;
private String name;
private Integer age;
private String phone;
private String address;
public Data(){}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
}
<强> DatasHandler
public class DatasHandler extends DefaultHandler {
private ArrayList<Data> alDatas;
private Data data;
private String reading;
public DatasHandler(){}
@Override
public void startElement(String uri, String localName, String qName,
Attributes attributes) throws SAXException {
if(qName.equals("maintag")){
alDatas = new ArrayList<>();
}
if(qName.equals("data")){
data = new Data();
}
}
@Override
public void endElement(String uri, String localName, String qName)
throws SAXException {
if(qName.equals("data")){
alDatas.add(data);
data = null;
}
if(qName.equals("id")){
data.setId(Integer.parseInt(reading));
}
if(qName.equals("name")){
data.setName(reading);
}
if(qName.equals("age")){
data.setAge(Integer.parseInt(reading));
}
if(qName.equals("phone")){
data.setPhone(reading);
}
if(qName.equals("address")){
data.setAddress(reading);
}
}
@Override
public void characters(char[] ch, int start, int length)
throws SAXException {
reading = new String(ch, start, length);
}
public ArrayList<Data> getAlDatas() {
return alDatas;
}
}
<强> XMLManager
public final class XMLManager {
public static ArrayList<Data> getAlDatas(){
ArrayList<Data> alDatas = null;
SAXParserFactory factory = SAXParserFactory.newInstance();
try {
SAXParser parser = factory.newSAXParser();
DatasHandler dHandler = new DatasHandler();
parser.parse(new File("D:\\Loic_Workspace\\SaxExample\\res\\test.xml"), dHandler);
alDatas = dHandler.getAlDatas();
} catch (ParserConfigurationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return alDatas;
}
}
主要
public class MyMain {
/**

*/
public static void main(String[] args) {
ArrayList<Data> alDatas = XMLManager.getAlDatas();
for(Data d:alDatas){
System.out.println(d.getName());
System.out.println(d.getId());
System.out.println(d.getAge());
System.out.println(d.getPhone());
System.out.println(d.getAddress());
System.out.println("--------------------");

您似乎想在Android上使用它。所以我认为您可以在XMLManager类中执行以下操作：
InputSource in = new InputSource(getResources().openRawResource(R.raw.data));
parser.parse(in, dHandler);
告诉我它是否有效，
