Méthode pour convertir un fichier XML en compétences NSData object_javascript

NSData *xmlData = [[NSData alloc]initWithContentsOfFile:[NSString stringWithFormat:@"%@/People.xml",[[NSBundle mainBundle] resourcePath]]]; 
  //2.将xmlData转化成xml文档 
  GDataXMLDocument *xmlDocument = [[GDataXMLDocument alloc]initWithData:xmlData options:0 error:nil]; 
  //3.得到节点 
  GDataXMLElement *rootElement = xmlDocument.rootElement; 
  //4.得到子节点 
/*NSArray *elementArray = rootElement.children; 
  //得到classone节点 
  GDataXMLElement *classoneElement = [elementArray firstObject]; 
  for(GDataXMLElement *element in classoneElement.children) 
  { 
    //得到当前节点的文本值 
    NSLog(@"%@",element.stringValue); 
    if (element.children.count>0) { 
      GDataXMLElement *infoElement = [element.children lastObject]; 
      //获得节点的所有属性和属性值 
      NSArray *attArray = infoElement.attributes; 
      for (GDataXMLElement *attElement in attArray) { 
        //得到属性名和属性值 
        NSLog(@"%@-%@",attElement.name,attElement.stringValue); 
      } 
    } 
  } 
  */ 
  //模糊查找 
  NSArray *eArray = [rootElement nodesForXPath:@"//info" error:nil]; 
  NSLog(@"%@",eArray); 

 xml字符串为：
<users>
<user name="hoge" age="20" />
<user name="fuga" age="30" />
</users>
 
//解析按钮事件
-(IBAction)btnXml
{
  
  NSString* str= [uitextview1 text];
  //string转成data
  NSData *xmlData = [str dataUsingEncoding: NSUTF8StringEncoding];
  //对xml进行解析需要使用NSXMLParser类，首先声明一个NSXMLParser对象  
  //开始解析 
  NSXMLParser* xmlRead = [[NSXMLParser alloc] initWithData:xmlData];//初始化NSXMLParser对象  
  [xmlRead setDelegate:self];//设置NSXMLParser对象的解析方法代理 
  [xmlRead parse];//调用代理解析NSXMLParser对象，看解析是否成功   
}
 
//解析器，从两个结点之间读取内容
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
  //NSLog(@"%@",string);
}
 
//获得结点结尾的值
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName
 namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
  //NSLog(@"%@",elementName);
}
//获得结点头的值
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName
 namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
  attributes:(NSDictionary *)attributeDict 
{
  //NSLog(@"%@",elementName);
  if([elementName isEqualToString: @"user"])
  {
    NSString* strName=[attributeDict valueForKey:@"name"];
    NSString* strAge=[attributeDict valueForKey:@"age"]; 
    NSString* strUser=uitextview2.text;
    strUser=[strUser stringByAppendingFormat:@"姓名：%@,年龄：%@\n",strName,strAge];
    [uitextview2 setText:strUser];
    //NSLog(@"姓名：%@,年龄：%@", strName,strAge);
  }
