1>.SAX解析方式(Simple API for XML)
#pragma mark 实现NSXMLParser的代理方法
#pragma mark 开始解析(打开文档)
-(void)parserDidStartDocument:(NSXMLParser *)parser
{
// 数组的初始化
self.xmlSAXArray = [NSMutableArray array];
}
#pragma mark 打开标签
-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if ([elementName isEqualToString:@"student"]) {
Student *student = [[Student alloc] init];
[self.xmlSAXArray addObject:student];
}
// 记录标签名字
_currentElement = elementName;
}
#pragma mark 取值
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
// NSLog(@"%@",string);
// 拿出数组中的学生对象
Student *student = [self.xmlSAXArray lastObject];
if ([_currentElement isEqualToString:@"name"]) {
student.name = string;
}else if ([_currentElement isEqualToString:@"sex"]){
student.sex = string;
}else if ([_currentElement isEqualToString:@"phone"]){
student.phone = string;
}
}
#pragma mark 关闭标签

#pragma mark 关闭文档

{

// 打印验证
for (Student *student in self.xmlSAXArray) {
NSLog(@"%@ %@ %@",student.name,student.sex,student.phone);
}
