网络解析之XML及JSON

首先要加入类库GDataXMLNode和JSON

解析本地文件Students.txt

<students>

<student>

<name>汤姆 </name>

<age>20</age>

<phone>13049640144</phone>

</student>

<student>

<name> 吉米</name>

<age>20</age>

<phone>13049640144</phone>

</student>

<student>

<name> 螺丝</name>

<age>20</age>

<phone>13049640144</phone>

</student>

</students>

//XML解析

NSString *str = [NSString stringWithContentsOfFile:[[NSBundle
mainBundle]pathForResource:@"Students"               ofType:@"txt"]
encoding:NSUTF8StringEncoding error:nil];

//解析XML，把结果放在document里面

GDataXMLDocument *document = [[GDataXMLDocument alloc]initWithXMLString:str options:0 error:nil];

GDataXMLElement *root = [document rootElement];//获得根结点

NSArray *arr = [root nodesForXPath:@"//name" error:nil];

//遍历节点

for(GDataXMLElement *name in arr)

{

NSLog(@"%@",[name stringValue]);

}

//Json解析

NSString *str = @"[{\"name\":\"kelly\",\"age\":\"23\",\"sex\":\"女\"},{\"name\":\"evnxy\",\"age\":\"21\",\"sex\":\"女\"}]";

NSArray *arr = [str JSONValue];

NSLog(@"%@",arr);
