使用NSXMLParser能不能解析只有一个node的xml？

Question

我研究了NSXMLParser，然后准备实现一下，解析XML文件，代码如下：

-(OneNodeXMLParser*)initOneNodeXMLParser{

appDelegate = (OneNodeXMLParser*)[[UIApplication sharedApplication]delegate];
return self;
}

-(void)parser:(NSXMLParser*) parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
NSLog(@"%s",__PRETTY_FUNCTION__,nil);
if([elementName isEqualToString:@"a"]){

}
NSLog(@"Starting processing");
}

-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{
NSLog(@"%s",__PRETTY_FUNCTION__,nil);
NSLog(@"%s",string);
}

   -(void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{
NSLog(@"%s",__PRETTY_FUNCTION__,nil);
NSLog(@"Finishing processing");
}

要成功解析应该改哪啊？

Answer 1

在.h文件中声明一个NSMutableString *store;

然后加下面的代码：

-(void)parser:(NSXMLParser*) parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
  if([elementName isEqualToString:@"a"])
  {
     store = [[NSMutableString alloc] init];
  }
  NSLog(@"Starting processing");
}

-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
  NSLog(@"%s",string);
   if (store != nil)
   {
     [store appendString:string];
   }
}

-(void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
 {
   NSLog(@"Finishing processing String : %@", store);
 }
