iOS对于XML的解析有系统自带的SDK--NSXMLParser,鄙人愚拙，只会用GDataXML进行解析，这里仅介绍GData的使用。(以下图为例)
1.对于一个xml文件，先读取出来
NSData *xmlData = [[NSFileManager defaultManager]contentsAtPath:[NSString stringWithFormat:@"%@/%@",[[NSBundle mainBundle] resourcePath],@"test.xml"]];
NSError *error;
GDataXMLDocument *document = [[GDataXMLDocument alloc] initWithData:xmlData options:0 error:&error];
2.取到要解析到的节点目录
NSString *path = @"/Users/user";
NSArray *arr = [document nodesForXPath:path error:nil];
//获取元素GDataXMLElement
GDataXMLElement *subElement = [arr lastObject];
//获取此节点下的name(如果此节点下是单一string可以这样)
NSString *name = [[[subElement elementsForName:@"name"]lastObject] stringValue];
//如果节点下是几个元素的，例如<name name1 = "aa" name2 = "aaa"/>
则应该
NSArray *userArr = [subElement elementsForName:@"name"];
for (GDataXMLElement *subElement in userArr) {
NSString *name1 = [[subElement attributeForName:@"name1"]stringValue];
NSString *name2 = [[subElement attributeForName:@"name2"]stringValue];
}
至此可解析完毕。
3.下面实例展示如果将一份全球国家地区和编码的xml文件转为plist文件
NSData *plistXML = [[NSFileManager defaultManager]contentsAtPath:[NSString stringWithFormat:@"%@/%@",[[NSBundle mainBundle] resourcePath],@"country_city_20151105.xml"]];
NSError *error;
GDataXMLDocument *doc = [[GDataXMLDocument alloc] initWithData:plistXML options:0 error:&error];
NSMutableDictionary *dict = [[NSMutableDictionary alloc]init];
NSString *path = @"/Location";
NSArray *locationArr = [doc nodesForXPath:path error:nil];
NSLog(@"locationArr = %@",locationArr);
for (GDataXMLElement *obj in locationArr) {
NSMutableArray *countryA = [[NSMutableArray alloc]init];
NSMutableArray *countryB = [[NSMutableArray alloc]init];
