/**
* 文件名:personInfo.xml
* 数据：
原理：
这种解析方式是利用它的代理NSXMLParserDelegate实现的
第一个代理方法：开始处理xml数据，它会把整个xml遍历一遍，识别元素节点名称
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict;
第二个代理方法：也就是得到文本节点里存储的信息数据
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string;
第三个代理方法：存储从第二个代理方法中获取到的信息
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
这就是解析的过程，在这个过程中会不停的重复的执行这三个代理方法，直到遍历完成
另外：
解析开始执行的方法
- (void)parserDidStartDocument:(NSXMLParser *)parser;
解析结束执行的方法
- (void)parserDidEndDocument:(NSXMLParser *)parser;
当出现解析错误的时候，会执行这个方法
- (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError;
