解析XML字符串SAX解析器机器人

Question

我有一个包含一个xml文件数据

字符串

如

<?xml version="1.0" encoding="UTF-8"?> 

<data> 

<type> 
<lory>vroom</lory> 
<car>crack</car> 
</type> 

<type> 
<lory>doom</lory> 
<car>chack</car> 
</type> 

</data> 

此被保持在名为标签字符串;

我使用SAX解析器来检索数据如下

SAXHelper sh = null; 

      try { 
       sh = new SAXHelper(newxml); 
      } catch (MalformedURLException e) { 
       e.printStackTrace(); 
      } 

      sh.parseContent(""); 

部分saxhelper类

class SAXHelper { 


     public HashMap<String, String> userList = new HashMap<String, String>(); 
     private String data; 

     public SAXHelper(String url1) throws MalformedURLException { 
      this.data = new String(url1); 
     } 

     public RSSHandler parseContent(String parseContent) { 
      RSSHandler df = new RSSHandler(); 
      try { 

       SAXParserFactory spf = SAXParserFactory.newInstance(); 
       SAXParser sp = spf.newSAXParser(); 
       XMLReader xr = sp.getXMLReader(); 
       xr.setContentHandler(df); 
       xr.parse(data); 

      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
      return df; 
     } 
    } 

的，但我与此错误显示错误畸形结束。简而言之，我想将一个xml字符串传递给sax解析器来设置并获取结果。

Answer 1

你传入原始的XML：

<?xml version="1.0" encoding="UTF- 

因此例外：
