场景：未为程序启动的时候配置一些记录文件，保存程序当时的状态。

+(void) CreateXmlFile{    NSXMLElement *root =[[NSXMLElement alloc] initWithName:@"group"];    NSXMLElement *family =[[NSXMLElement alloc] initWithName:@"family" stringValue:@"家人"];    NSXMLElement *friend =[[NSXMLElement alloc] initWithName:@"friend"];    NSXMLElement *classmate =[[NSXMLElement alloc] initWithName:@"classmate" stringValue:@"同学"];    NSXMLElement *worker =[[NSXMLElement alloc] initWithName:@"worker" stringValue:@"同事"];    NSXMLElement *fellowVillager =[[NSXMLElement alloc] initWithName:@"fellowVillager" stringValue:@"老乡"];    NSXMLElement *stranger =[[NSXMLElement alloc] initWithName:@"stranger" stringValue:@"陌生人"];        [root addChild:family];    [root addChild:friend];    NSXMLElement *item1 =[[NSXMLElement alloc] initWithName:@"item1" stringValue:@"张三"];    NSXMLElement *item2 =[[NSXMLElement alloc] initWithName:@"item2" stringValue:@"李四"];    NSXMLElement *item3 =[[NSXMLElement alloc] initWithName:@"item3" stringValue:@"王五"];    [friend addChild:item1];    [friend addChild:item2];    [friend addChild:item3];        [root addChild:classmate];    [root addChild:worker];    [root addChild:fellowVillager];    [root addChild:stranger];           NSXMLDocument *xmlRoot =[[NSXMLDocument alloc] initWithRootElement:root];    [root release];    NSData *data =[xmlRoot XMLData];    [data writeToFile:@"/Users/mac/work/pratise/12.xml" atomically:NO];    [xmlRoot release];        }
