尝试 iOS 版 NSXMLParser:https://developer.apple.com/library/ios/documentation/cocoa/reference/foundation/Classes/NSXMLParser_Class/Reference/Reference.html

你在这里有一个教程:http://iphonebyradix.blogspot.com/2011/08/parsing-xml-using-nsxmlparser.html

此委托(delegate)方法为您获取标签内的字符串

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

此方法为您获取案例中的属性 enclosure_details 中的 url

- (void)parser:(NSXMLParser *)parser foundAttributeDeclarationWithName:(NSString *)attributeName forElement:(NSString *)elementName type:(NSString *)type defaultValue:(NSString *)defaultValue;
