我有以下链接，从以下链接返回 XML

    http://api.wunderground.com/auto/wui/geo/WXCurrentObXML/index.xml?query=24.827774,67.034367    //This is URLString link

     NSXMLParser *xmlParser=[[NSXMLParser alloc] initWithContentsOfURL:[NSURL URLWithString:
                                                             [NSString stringWithFormat:@"%@",URLString]]]; 
    [xmlParser setDelegate:self];
    [xmlParser parse];



 - (void)parser:(NSXMLParser *)parser 
               didStartElement:(NSString *)elementName 
               namespaceURI:(NSString *)namespaceURI 
               qualifiedName:(NSString *)qualifiedName 
           attributes:(NSDictionary *)attributeDict {



 - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {

 - (void)parser:(NSXMLParser *)parser 
               didEndElement:(NSString *)elementName
               namespaceURI:(NSString *)namespaceURI 
               qualifiedName:(NSString *)qName {

我只想保存“城市”“天气”“temp_f”和“temp_c”的值，以便在标签上显示；

我真的对 NSXMLParser 解析总是感到困惑，如果有人能用好词来定义，我将不胜感激，以便我对 NSXMLParser 得到正确的理解

提前谢谢

I have following link, returning XML as from following link

    http://api.wunderground.com/auto/wui/geo/WXCurrentObXML/index.xml?query=24.827774,67.034367    //This is URLString link

     NSXMLParser *xmlParser=[[NSXMLParser alloc] initWithContentsOfURL:[NSURL URLWithString:
                                                             [NSString stringWithFormat:@"%@",URLString]]]; 
    [xmlParser setDelegate:self];
    [xmlParser parse];



 - (void)parser:(NSXMLParser *)parser 
               didStartElement:(NSString *)elementName 
               namespaceURI:(NSString *)namespaceURI 
               qualifiedName:(NSString *)qualifiedName 
           attributes:(NSDictionary *)attributeDict {



 - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {

 - (void)parser:(NSXMLParser *)parser 
               didEndElement:(NSString *)elementName
               namespaceURI:(NSString *)namespaceURI 
               qualifiedName:(NSString *)qName {

I want to save only values of "city" "weather" "temp_f" and "temp_c" so for displaying on labels;

I am really get confuse always about NSXMLParser parsing, I would be thankful if someone will define in good words, so that I get proper understanding of NSXMLParser

Thank you in Advance

在您的 didEndElement 委托方法中检查 elementName。

if (elementName isEqualtoString:@"city"])
// Save the element which is currently holding the value from the `foundCharacters` delegate method into your variable.

您可以对所需的其他值执行相同的操作。

In your didEndElement delegate method check for the elementName.

if (elementName isEqualtoString:@"city"])
// Save the element which is currently holding the value from the `foundCharacters` delegate method into your variable.

You can do the same for the other values you want.
