【IOS】 XML解析和xml转plist文件(GDataXML)

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];

if (countryArr.count) {

for (GDataXMLElement *subElement in countryArr) {

NSString *NameString = [[subElement attributeForName:@"Name"]stringValue];

NSString *codeStr = [[subElement attributeForName:@"Code"]stringValue];

NSString *regionCodeStr = [[subElement attributeForName:@"regionCode"]stringValue];

NSLog(@"NameString = %@ codeStr = %@ regionCodeStr = %@",NameString,codeStr,regionCodeStr);

NSString *tmpStr = [NSString stringWithFormat:@"%@+%@",NameString,regionCodeStr];
