使用RXMLElement工具類解析XML
阿新 • • 發佈：2018-12-31
現在來寫一篇我最近使用過的一種XML解析的方法的文章。XML解析有多種多樣的方法，包括蘋果自帶的方法和各種工具類，今天我只介紹用RXMLElement的工具類來解析XML。
使用步驟：
1.首先把XML解析類匯入工程；
2.然後在加入框架libxml2.dylib；
3.最後把Header search Paths的路徑設定一下：/usr/include/libxml2
最後上程式碼：
//MARK:解析xml - (void)analysisXmlContents{ // NSString *xmlFileString = [[NSBundle mainBundle] pathForResource:@"app" ofType:@"xml"]; // // NSData *xmlData = [NSData dataWithContentsOfFile:xmlFileString]; // // NSString*conte=[NSString stringWithContentsOfFile:xmlFileString encoding:NSUTF8StringEncoding error:nil]; // stringcontents=conte; //獲取儲存的檔案路徑 NSString*filepath=[[NSHomeDirectory()stringByAppendingPathComponent:@"Documents"]stringByAppendingPathComponent:@"app.xml"]; //獲取檔案內容 NSString*conte=[NSString stringWithContentsOfFile:filepath encoding:NSUTF8StringEncoding error:nil]; stringcontents=conte; if ([self isBlankString:stringcontents]) { NSString *xmlFileString = [[NSBundle mainBundle] pathForResource:@"app" ofType:@"xml"]; NSString*conte=[NSString stringWithContentsOfFile:xmlFileString encoding:NSUTF8StringEncoding error:nil]; stringcontents=conte; } if([self isBlankString:stringcontents]) { return; }else { } //解析檔案內容 NSLog(@"path=%@",filepath); RXMLElement*rootxml=[RXMLElement elementFromXMLString:stringcontents encoding:NSUTF8StringEncoding]; self.allArray=[NSMutableArray arrayWithCapacity:0]; self.allArray2=[NSMutableArray arrayWithCapacity:0]; self.allArray3=[NSMutableArray arrayWithCapacity:0]; self.yijiArray=[NSMutableArray arrayWithCapacity:0]; self.yijiArray2=[NSMutableArray arrayWithCapacity:0]; self.yijiArray3=[NSMutableArray arrayWithCapacity:0]; self.erjiArray=[NSMutableArray arrayWithCapacity:0]; self.sanjiArray=[NSMutableArray arrayWithCapacity:0]; self.erjiarray=[NSMutableArray arrayWithCapacity:0]; self.sanjiarray=[NSMutableArray arrayWithCapacity:0]; //解析資料 [rootxml iterate:@"Content" usingBlock:^(RXMLElement*xmlContent){ NSString*contents_ele=[xmlContent attribute:@"Name"]; if([contents_ele isEqualToString:@"OnArea11Light"]){ kaizhaomingAction=[xmlContent attribute:@"Action"];
