How to save multiple xml files in cache file path in ios?

Im saving xml file in cache file path as follows:

// Determile cache file path
 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
 filePathl = [NSString stringWithFormat:@"%@/%@", [paths objectAtIndex:0],@"list.xml"];   

// Download and write to file
 NSURL *url = [NSURL URLWithString:detail_product_listing_rss];
 NSData *urlData = [NSData dataWithContentsOfURL:url];
 [urlData writeToFile:filePathl atomically:YES];

But using this code i can retrive data of recently used xml file.Could anybody please tell me how to save multiple xml files for offline use?

You need to save the xml with different names. Else it'll overwrite old xml.

Keep a integer value for this purpose, if you want this after the app restart also keep it in NSUserDefaults.

 int posValue = [[[NSUserDefaults standardUserDefaults] objectForKey:@"lastXml"] intValue];

 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
 filePathl = [NSString stringWithFormat:@"%@/list_%d.xml", [paths objectAtIndex:0],posValue];   

 NSURL *url = [NSURL URLWithString:detail_product_listing_rss];
 NSData *urlData = [NSData dataWithContentsOfURL:url];
 [urlData writeToFile:filePathl atomically:YES];

 [[NSUserDefaults standardUserDefaults] setObject:[NSNumber numberWithInt:posValue+1] forKey:@"lastXml"];
