我正在实现一个基于客户端的应用程序。其中有一个XML字符串,我需要将其转换为JSON格式并发送到服务器。我不知道如何进行转换。请问你们能否向我提供任何文档或想法?
第一步:将XML读入NSDictionary中:http://troybrant.net/blog/2010/09/simple-xml-to-nsdictionary-converter/
第二步:将NSDictionary转换成JSON:http://code.google.com/p/json-framework/
// Don't forget the imports ;)
#import "XMLReader.h"
// You must have a XML string from somewhere
NSString XMLString = yourXML;
// I remove all returns and tabs from the text, after i would be annoying if you don't remove it
XMLString = [XMLString stringByReplacingOccurrencesOfString:@"\r" withString:@""];
XMLString = [XMLString stringByReplacingOccurrencesOfString:@"\t" withString:@""];
// Parse the XML into a dictionary
NSError *parseError = nil;
NSDictionary *xmlDictionary = [XMLReader dictionaryForXMLString:XMLString error:&parseError];
NSError *error;
self.dataParsed = [NSJSONSerialization dataWithJSONObject:xmlDictionary
options: NSJSONWritingPrettyPrinted // Pass 0 if you don't care about the readability of the generated string
error:&error];
// Print the dictionary
NSLog(@"%@", xmlDictionary);
