这里使用NSXMLParser来解析,这个是apple自带的xml解析库,有个参考文章:http://www.raywenderlich.com/553/xml-tutorial-for-ios-how-to-choose-the-best-xml-parser-for-your-iphone-project
在Xcode中加入一个xml文件:
<?xml version="1.0" encoding="ISO-8859-1"?> <root> <Shop shoplocation="beijing"> <id>001</id> <name>John</name> <url>Reminder</url> <info>Don't forget the meeting!</info> </Shop> <Shop shoplocation="dongcheng"> <id>002</id> <name>Jack</name> <url>cc</url> <info>how are you!</info> </Shop> <Shop shoplocation="haidian"> <id>003</id> <name>Tom</name> <url>bb</url> <info>I am fine!</info> </Shop> </root>
