XML与JSON的转换

-(void)test {

    

    //XML文本范例

    NSString *testXMLString = @"Cake0.55RegularChocolateBlueberryNoneGlazedSugar";

    

    NSLog(@"xml string[\n%@\n]", testXMLString);

    // 解析XML为NSDictionary

    NSError *parseError = nil;

    NSDictionary *xmlDictionary = [XMLReader dictionaryForXMLString:testXMLString error:&parseError];

    // 打印 NSDictionary

    NSLog(@"%@", xmlDictionary);

    

    //NSDictionary转换为Data

    NSData* jsonData = [NSJSONSerialization dataWithJSONObject:xmlDictionary options:NSJSONWritingPrettyPrinted error:&parseError];

    

    //Data转换为JSON

    NSString* str = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

    

    NSLog(@"jsonData string[\n%@\n]", str);

    //字符组转换为NSDictionary

    NSDictionary *jsonDict = [str objectFromJSONString];

    

    //NSDictionary转换为XML的plist格式

    NSData *xmlData = [NSPropertyListSerialization dataFromPropertyList:jsonDict

                                                                 format:NSPropertyListXMLFormat_v1_0

                                                       errorDescription:NULL];

    

    //Data转换为NSString输出 编码为UTF-8

    NSLog(@"XML: %@", [[NSString alloc] initWithData:xmlData encoding:NSUTF8StringEncoding]);

    

    

   

    NSLog(@"%@",[XMLWriter XMLStringFromDictionary:jsonDict withHeader:NO]);

 

}

 

//其中用到了三个类库，分别为

1，JSONKit       https://github.com/johnezang/JSONKit

2，XMLWriter    https://github.com/ahmyi/XMLWriter

3，XMLReader   https://github.com/amarcadet/XMLReader
