IOS GDataXML 解析xml

配置过程：

(1).引入GDataXML(4个文件)

<arc模式下>.对GDataXML.m增加非arc注释 -fno-objc-arc

(2).添加系统库 libxml2.dylib

(3).Head Search Path中添加 /usr/include/libxml2

(4).Other linker flags中添加 -lxml2

(5).xml格式

==================================

<?xml version="1.0" encoding="utf-8"?>

<Users>

<User id="001">

<name>Ryan</name>

<age>24</age>

</User>

<User id="002">

<name>Tang</name>

<age>23</age>

</User>

</Users>

==================================

(6).应用

==================================

//获取工程目录的xml文件

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"users" ofType:@"xml"];

NSData *xmlData = [[NSData alloc] initWithContentsOfFile:filePath];

//使用NSData对象初始化

GDataXMLDocument *doc = [[GDataXMLDocument alloc] initWithData:xmlData options:0 error:nil];

//获取根节点（Users）

GDataXMLElement *rootElement = [doc rootElement];

//获取根节点下的节点（User）

NSArray *users = [rootElement elementsForName:@"User"];

for (GDataXMLElement *user in users) {

//User节点的id属性

NSString *userId = [[user attributeForName:@"id"] stringValue];

NSLog(@"User id is:%@",userId);

//获取name节点的值

GDataXMLElement *nameElement = [[user elementsForName:@"name"] objectAtIndex:0];

NSString *name = [nameElement stringValue];

NSLog(@"User name is:%@",name);

//获取age节点的值

GDataXMLElement *ageElement = [[user elementsForName:@"age"] objectAtIndex:0];

NSString *age = [ageElement stringValue];

NSLog(@"User age is:%@",age);

NSLog(@"-------------------");
