Question

我尝试使用NSXMLParser类解析XML格式的NSString，但我无法分析它。它只显示第一个标签（元素）的元素当我解析XML文件中的内容时，我得到了所有元素。

#import "Parser.h"
#import "DeviceConfig.h"

@implementation Parser

@synthesize curElement;
@synthesize value;
@synthesize defaultValue;

-(id) initWithXMLData: (NSString*) data {
    if(self == [super init]) {
        xmlData = data;
        NSData* xmlNSData = [xmlData dataUsingEncoding:NSUTF8StringEncoding];
        cameraOptions = [[NSMutableDictionary alloc] init];
        parser = [[NSXMLParser alloc] initWithData:xmlNSData];
        [parser setDelegate: self];
        [parser parse];
    }
    return self;
}

- (NSMutableDictionary*) getCameraOptions {
    return cameraOptions;
}

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

- (void) parser: (NSXMLParser*) parser didEndElement:(nonnull NSString *)elementName namespaceURI:(nullable NSString *)namespaceURI qualifiedName:(nullable NSString *)qName {
    NSLog(@"ended element : %@", elementName);
}

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

}

@end

主

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        Parser* p = [[Parser alloc] initWithXMLData:@"<?xml version=\"1.0\" encoding=\"utf-8\"?><flash></flash><torch></torch>"];
    }
    return 0;
}

使用NSXMLParser通过NSString解析xml
