J2ME KXML 解析中文xml代码示例

1、首先需要在你的工程资源中引入kxml.zip(kxml 1.21 stable version)

http://kxml.objectweb.org/software/downloads/  

2、然后你建立一个httpconnection发送url请求，返回为in

3、最后解析in内容，如果包含中文内容，注意需要设置读入字节格式为UTF-8，否则会出现乱码。

比如从google cn上寻找一个酒店，需要获取其名字，地址，电话，坐标信息，输出格式为kml，url请求为

http://ditu.google.cn/maps?output=kml&hl=zh-CN&sll=31.2309321,121.4755366&start=0&num=10&q=酒店

那么解析返回kml信息的代码片断如下：

public void parse(InputStream in) throws IOException {
            System.out.println("Enter parse:in");
     Reader reader = new InputStreamReader(in,"UTF-8");
     XmlParser parser = new XmlParser(reader);
     ParseEvent pe = null;   
     parser.skip();   
     parser.read(Xml.START_TAG, null, "kml");
     parser.skip();   
     parser.read(Xml.START_TAG, null, "Folder");
     boolean trucking = true;   
     //boolean first = true;   
     while (trucking) {
       pe = parser.read();     
       if (pe.getType() == Xml.START_TAG) {
         String name = pe.getName();       
         if (name.equals("Placemark")) {
           String title, address, coordinates, snippet, tel;
           title = address = coordinates = snippet = tel = null;
           while ((pe.getType() != Xml.END_TAG) ||
               (pe.getName().equals(name) == false)) {
             pe = parser.read();           
             if (pe.getType() == Xml.START_TAG &&
                 pe.getName().equals("name")) {
               pe = parser.read();
                      title = pe.getText();
             }
             else if (pe.getType() == Xml.START_TAG &&
                 pe.getName().equals("coordinates")) {
               pe = parser.read();             
               coordinates = pe.getText();
             }
             else if (pe.getType() == Xml.START_TAG &&
                 pe.getName().equals("Snippet")) {
               pe = parser.read();
                      snippet = pe.getText();
                      //简述的格式是 "address<br/>tel no"
                      int beg = snippet.indexOf("<");
                      int end = snippet.indexOf(">");
                      address = snippet.substring(0,beg);
                      tel = snippet.substring(end,snippet.length());
             }
           }

                  // 这里的Listener是处理xml解析结果的抽象接口，通常由对xml感兴趣的Form对象实现
                  mResultListener.itemParsed(title, address, coordinates, tel);
         }
         else {
           while ((pe.getType() != Xml.END_TAG) ||
               (pe.getName().equals(name) == false))           
            pe = parser.read();       
           }
       }
       if (pe.getType() == Xml.END_TAG &&
             pe.getName().equals("kml"))
        trucking = false;   
     }
   }
