这里主要介绍一下由Google提供的一种在IOS平台上进行XML解析的开源库GdataxML，可以到http://code.google.com/p/gdata-objectivec-client/source/browse/trunk/Source/XMLSupport/下载源码，下载下来后进入文件夹找到XMLSupport文件夹，将里面的GdataxMLNode.h和GdataxMLNode.m文件拖拽到项目

注：

1.targets ->build settings 的other linker flags 添加字段 -lxml2

2.targets ->build settings 的headersearch Paths 添加字段/usr/include/libxml2

3.导入 libxml2.dylib 系统库

例如解析:

<?xml version="1.0" encoding="utf-8"?>
<Users>
    <User id="001">
        <name>Ryan</name>
        <name>hjhj</name>
        <age>24</age>
    </User>
    <User id="002">
        <name>Tang</name>
        <name>Tangss</name>
        <age>23</age>
    </User>
    <User id="003">
        <name>Tanssg</name>
        <name>Tansdsg</name>
        <age>2ssss3</age>
    </User>
</Users>

使用GdataxMLNode 解析

@H_301_92@//获取工程目录xml文件 NSString *filePach = [[NSBundle mainBundle]pathForResource:@"Users" ofType:@"xml"]; NSData *xmlData = [[NSData alloc]initWithContentsOfFile:filePach]; //使用nsdata对象初始化 GdataxMLDocument *doc = [[GdataxMLDocument alloc]initWithData:xmlData options:0 error:nil]; //获得跟节点(Users) GdataxMLElement *rootElement = [doc rootElement]; //获取跟节点下的节点 NSArray *users = [rootElement elementsForName:@"User"]; for (GdataxMLElement *user in users) { //user节点属性 NSString *userId =[[user attributeForName:@"id"]stringValue]; NSLog(@"userId = %@",userId); //获取name节点的值 GdataxMLElement *nameElement = [[user elementsForName:@"name"]objectAtIndex:1]; NSString *name = [nameElement stringValue]; NSLog(@"name = %@",name); //获取age节点的值 GdataxMLElement *ageElement = [[user elementsForName:@"age"]objectAtIndex:0]; NSString *age = [ageElement stringValue]; NSLog(@"age = %@",age); NSLog(@"==================="); }
