如何使用NSXMLParser解析多个XML标记

#import <Foundation/Foundation.h>

@interface XMLParserDelegate : NSObject<NSXMLParserDelegate>

@end

@implementation XMLParserDelegate

- (void)parserDidStartDocument:(NSXMLParser *)parser {
    NSLog(@"解析开始");
}

- (void)parserDidEndDocument:(NSXMLParser *)parser {
    NSLog(@"解析结束");
}

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(nullable NSString *)namespaceURI qualifiedName:(nullable NSString *)qName attributes:(NSDictionary<NSString *, NSString *> *)attributeDict {
    NSLog(@"开始标记：%@", elementName);
    NSLog(@"属性：%@", attributeDict);
}

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(nullable NSString *)namespaceURI qualifiedName:(nullable NSString *)qName {
    NSLog(@"结束标记：%@", elementName);
}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
    NSLog(@"文本内容：%@", string);
}
