我是新手机编程。我有xml数据,我已经显示如下。使用该数据我想显示具有2个表的特定日期数据如何在单行中显示特定日期数据。在下一个数据2012 -06-20有3个表如何在第二行显示3tables数据。如何解析数据,告诉我逻辑

    2012-09-19 ->Having 2 tables(i.e Table1,Table2)
    2013-09-20 ->Having 3 tables(i.e Table3,Table4,Table5)
    2013-09-21 ->Having 2 tables(i.e Table6,Table7)

现在我的问题是在上面的xml数据中我在该table1中共有7个表,table2数据属于2012-09-19 date.I想要解析数据并在下面显示如下所示

                                  CreateBy  SalesDailyAmount  PurchasesDailyAmount
   2012-09-19 ->Want to display      1           100                0.0000

使用以下代码

-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qName
       attributes: (NSDictionary *)attributeDict
    {
         if( [elementName isEqualToString:@"CreateBy"])
        {
               if(!soapResults)
            {
                soapResults = [[NSMutableString alloc] init];
            }
            xmlResults = YES;
        }
        if( [elementName isEqualToString:@"SalesDailyAmount"])
        {
               if(!soapResults)
            {
                soapResults = [[NSMutableString alloc] init];
            }
            xmlResults = YES;
        }      
        if( [elementName isEqualToString:@"PurchasesDailyAmount"])
        {
               if(!soapResults)
            {
                soapResults = [[NSMutableString alloc] init];
            }
            xmlResults = YES;
        }
    }
    -(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
    {
        if( xmlResults )
        {
            [soapResults appendString: string];
             NSLog(@"soap result %@",soapResults);
             [arr_detail addObject:soapResults];
            NSLog(@"gg %@",arr_detail);
            NSLog(@"gcvxg %@",arr_info);
        }
        [tableView reloadData];
    }
    -(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
    {
         if( [elementName isEqualToString:@"CreateBy"])
                {
                    xmlResults = FALSE;
                    [aslam4 addObject:soapResults];
                    NSLog(@"hello %@",aslam4);
                    soapResults = nil;
                }
                if( [elementName isEqualToString:@"SalesDailyAmount"])
                {
                    xmlResults = FALSE;
                    [aslam5 addObject:soapResults];            
                    NSLog(@"hello %@",aslam5);
                    soapResults = nil;
                }
              if( [elementName isEqualToString:@"PurchasesDailyAmount"])
                {
                    xmlResults = FALSE;
                    [aslam6 addObject:soapResults];
                      NSLog(@"hello %@",aslam6);
                    soapResults = nil;
                }
            }
    }

使用上面的代码我可以获得如下所示的数据

 OutPut
 CreateBy  SalesDailyAmount  PurchasesDailyAmount
     1           100                0.0000
     1           100                0.0000
     2           200                0.0000
     2           200                0.0000
     2           200                0.0000
     3           150                0.0000
     3           150                0.0000

但我想在下面显示如下

        CreateBy  SalesDailyAmount  PurchasesDailyAmount
  2012-09-19 ->Want to display      1           100                0.0000
  2012-09-20 ->Want to display      2           200                0.0000
  2012-09-21 ->Want to display      3           150                0.0000

我不想显示多个时间。在2012-09-19有2个表但两个都有相同的数据,但我不想多次显示。 同样2012-09-20在这里有3个表我也不想显示3次我想在一行中的3个表数据中显示。 总的来说我想说 现在在数组中它的存储数据如下所示 数组= {100,100,200,200,200,150,150},但我不想这样我想存储像这样的数组= {100,200,150} 请告诉我如何为此编写逻辑。

为了从数组中获取唯一值,请使用以下方法。

// Your array containing all values
NSArray *dataListArray = [[NSArray alloc] initWithObjects:@"100", @"100", @"200", @"200", @"200", @"300", @"300", @"300", nil];

// Array containing unique data.
NSArray *uniqueDataArray = [[NSSet setWithArray:dataListArray] allObjects];

根据您的要求,我认为 happle 是解决您问题的好方法。要使用 happle 类,您必须从github下载。重要的部分是xpath的概念。 所以一定要使用xpath。

检索日期

     NSString *cafeDateTime = @"//table"; 
NSMutableArray *newTutorials = [[NSMutableArray alloc] initWithCapacity:0];
for (TFHppleElement *element in tutorialsNodes) {    
    cafeDateTime = [element objectForKey:@"cafeDateTime"];

}
等等...... 如需了解更多信息,请访问此网站http://www.raywenderlich.com/14172/how-to-parse-html-on-ios

我遵循解析xml甚至复杂xml数据的简单方法:

  1. 将XMLReader库包含到您的项目中。 https://github.com/amarcadet/XMLReader
  2. 传递xml数据或xml文件路径,将xml数据转换为NSdata。

    NSString * path = [[NSBundle mainBundle] pathForResource:@“xmlExample”ofType:@“xml”];

    NSData * xmlData = [NSData dataWithContentsOfFile:path];

  3. 使用库函数获取正确的数据,分别标记为NSDictionary。

    NSDictionary * dict = [XMLReader dictionaryForXMLData:xmldata                                              选项:XMLReaderOptionsProcessNamespaces                                                误差:&安培;错误];

  4. 现在使用NSDictionary为你工作

    NSArray * arr = [dict valueforkey:@“xtag.ytag.z.tag”];

    你将获得ztag下的数组数组/数组。

    NSArray * arr = [dict valueforkey:@“xtag.ytag”];

    你将获得ytag下的数组数组/数组。

  5. 在很多项目中,它对我很有用,问题是“逻辑中的运行时错误”如果存在单行或数组的数组,则键的NSDictionary值可能会返回数组。

  6. 我使用特殊处理来解决这个问题。

  7. 总体而言,只需15分钟就可以顺利地读取xml数据,甚至是复杂的嵌套xml数据。

  8. 此外,如果想要编写XML数据,我使用XMLWriter

  9. 进行引用
