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)
Now what is my question is In above xml data i have total 7 tables in that table1,table2 data belong to 2012-09-19 date.I want to parse data and display in view like this below
CreateBy SalesDailyAmount PurchasesDailyAmount
2012-09-19 ->Want to display 1 100 0.0000
Using below code
-(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;
}
}
}
Using above code i can able to get data like this below
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
But i want to display like this below
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

Simple method which i follow to parse xml even complex xml data:
- Include XMLReader library to your project. https://github.com/amarcadet/XMLReader
Pass your xml data or xml file path to convert xml data to NSdata .
NSString *path = [[NSBundle mainBundle] pathForResource:@"xmlExample" ofType:@"xml"];
NSData *xmlData = [NSData dataWithContentsOfFile:path];
Use library function to get proper data, seperated tag wise to NSDictionary.
NSDictionary *dict = [XMLReader dictionaryForXMLData:xmldata options:XMLReaderOptionsProcessNamespaces error:&error];
Now use NSDictionary to work for you
NSArray *arr = [dict valueforkey: @"xtag.ytag.z.tag"];
you will get array/array of array of values under ztag .
NSArray *arr = [dict valueforkey: @"xtag.ytag"];
you will get array/array of array of values under ytag.
It is working great for me in many project's the issue is "Runtime error in our logic" NSDictionary value for key may return array if there is single row or array else array of array .
I handle this issue using exceptional handling.
Overall it will only take 15 minutes to work smoothly to read xml data, even complexly nested xml data.
Also if want to write XML data, i refer using XMLWriter

According to your requirement, i think happle is good solution for ur problems. For using the happle class you have to download from github. The important part is concept of xpath. so be sure to use of xpath.
To retrieve the date
NSString *cafeDateTime = @"//table";
NSMutableArray *newTutorials = [[NSMutableArray alloc] initWithCapacity:0];
for (TFHppleElement *element in tutorialsNodes) {
cafeDateTime = [element objectForKey:@"cafeDateTime"];
}
so on.. For more plz visti this site http://www.raywenderlich.com/14172/how-to-parse-html-on-ios

In order to get the unique values from array use the follwing method.
// 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];
