XML文件转化成NSData对象的方法

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 
 
  //模糊查找 
  NSArray *eArray = [rootElement nodesForXPath:@"//info" error:nil]; 
  NSLog(@"%@",eArray); 

iPhone开发 解析xml NSData

具体内容请看下文代码分析：

 xml字符串为：




 
//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);
  }
}
