[balkarov]

htmlDataParser = [TFHpple hppleWithHTMLData:htmlData];
xpathQueryString = @"//div[@class='top']";

htmlNodes = [htmlDataParser searchWithXPathQuery:xpathQueryString];
NSString *imageUrl;

for (TFHppleElement* element in htmlNodes) {
    imageUrl = [element objectForKey:@"style"];
}

NSRange r1 = [imageUrl rangeOfString:@"url("];
NSRange r2 = [imageUrl rangeOfString:@")"];
NSRange rSub = NSMakeRange(r1.location + r1.length, r2.location - r1.location - r1.length);
imageUrl = [imageUrl substringWithRange:rSub];
