If I understand you correctly you want to find all xml files in all folders in the documents directory?

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;

NSArray *contents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory
                                                                        error:nil];
for (NSString *path in contents) {
    BOOL isDir;
    if ([[NSFileManager defaultManager] fileExistsAtPath:path
                                             isDirectory:&isDir]
        && isDir) {
        // directory in documents directory
        NSArray *dirContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:path
                                                                                   error:nil];
        for (NSString *dirContentsPath in dirContents) {
            if ([[dirContentsPath pathExtension] isEqualToString:@"xml"]) {
                NSLog(@"xml found: %@", dirContentsPath);
            }
        }
    }
}

You might want to add recursion for deeper directories.

To get List of directories use following code, there is 1 attribute isDirectory which gives you true/false for folder/file.

NSFileManager *fileManager = [NSFileManager defaultManager];
fileList = [[fileManager directoryContentsAtPath:PATH_TO_SEARCH] retain];
NSMutableArray *arrDirectory = [[NSMutableArray alloc] init];
for(NSString *file in fileList) 
{
    NSString *path = [PATH_TO_SEARCH stringByAppendingPathComponent:file];
    BOOL isItDirectory = NO;
    [fileManager fileExistsAtPath:path isDirectory:(&isItDirectory)];
    if(isItDirectory)
        [arrDirectory addObject:file];
}

your array will contain all the directory list here. You can follow same pattern for xml files.

Hope this helps.
