一、kissXML的github地址
https://github.com/robbiehanson/KissXML
二、使用前注意?
项目要导入libxml2.dylib。另运行时提示"libxml/tree.h"找不到,需要在项目的Build Settings搜索Header S,将Header Search Paths项设置为:/usr/include/libxml2。
三、kissXML的简单使用
1、xml文件如下:
2、几个方法使用举例
#import"DDXML.h" #import"DDXMLElementAdditions.h" @implementation ViewController //解析XML staticNSString *kXML =@"//District//Province"; - (void)viewDidLoad { [super viewDidLoad]; NSString *path =[[NSString alloc] initWithString:[[NSBundle mainBundle] pathForResource:@"ProvinceCity" ofType:@"xml"]] NSData *data = [[NSData alloc] initWithContentsOfFile:path]; [self parsedDataFromData:data andProvince:@"江西省"]; [self parsedDataFromData:data]; } //取特定省份下包含所有城市 -(void)parsedDataFromData:(NSData *)data andProvince:(NSString *)province{ DDXMLDocument *doc = [[DDXMLDocument alloc] initWithData:data options:0error:nil]; /////解析 NSArray *items = [docnodesForXPath:kXMLerror:nil]; for (DDXMLElement *objin items) { DDXMLNode *aUser = [obj attributeForName:@"Name"];//取属性Name的值 if ([aUser.stringValueisEqualToString:province]) { NSArray *CityLst = [obj elementsForName:@"City"];//取城市点点列表,保存到数组中 if(CityLst.count>0)//第二层 { for (DDXMLElement *citysin CityLst) { DDXMLNode *citynode=[citys attributeForName:@"Name"]; NSLog(@"%@",citynode.stringValue); } } } } } //取所有省份及其下级节点,包含修改操作 - (void)parsedDataFromData:(NSData *)data{ DDXMLDocument *doc = [[DDXMLDocument alloc] initWithData:data options:0 error:nil]; /////解析 NSArray *items = [doc nodesForXPath:kXML error:nil]; for (DDXMLElement *obj in items) { DDXMLNode *aUser = [obj attributeForName:@"Name"];//取属性Name的值 //[aUser setStringValue:@"haha!"];//修改属性节点的值 [obj addAttribute:[DDXMLNodeattributeWithName:@"test"stringValue:@"wzh"]];//增加一个属性节点 [obj addAttributeWithName:@"ttt"stringValue:@"343"];//再增加一个属性节点 //[obj setStringValue:@"NewNode"];//设置当前节点的值 DDXMLNode *newnode=[DDXMLNode elementWithName:@"newNode"];//设置一个新的节点 [obj addChild:newnode];//给obj添加一个节点 DDXMLElement *newdxml = [[obj elementsForName:@"newNode"] objectAtIndex:0];//访问刚刚添加的节点 [newdxml addAttributeWithName:@"nodetwo"stringValue:@"twovalue"];//给刚添加的节点增加增的下级节点,并且下级节点再一个属性值 DDXMLNode *newnode2=[DDXMLNode elementWithName:@"newNode2" stringValue:@"hello!"]; [newdxmladdChild:newnode2]; } //保存到沙盒目录下 NSString *path =[[NSStringalloc]initWithFormat:@"%@/xmlData.xml", [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES) objectAtIndex:0]]; NSString *result=[[NSStringalloc]initWithFormat:@"%@",doc]; [resultwriteToFile:pathatomically:YESencoding:NSUTF8StringEncoding error:nil]; }
四、补充,如何把资源文件放到documents目录下。(验证未成功,求答案??)
BOOL success; NSFileManager *fileManager = [NSFileManager defaultManager]; NSError *error; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *writableDBPath = [documentsDirectory stringByAppendingPathComponent:DATABASE_FILENAME]; success = [fileManager fileExistsAtPath:writableDBPath]; if (success) return; // The writable database does not exist, so copy the default to the appropriate location. NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:DATABASE_FILENAME]; success = [fileManager copyItemAtPath:defaultDBPath toPath:writableDBPath error:&error]; if (!success) { ////NSAssert1(0, @"Failed to create writable database file with message ‘%@‘.", DATABASE_FILENAME ); }
