URL meta tags parsing (WIP)

       let urlString = "http://www.nytimes.com/2016/04/07/us/politics/donald-trump-and-hillary-clinton-look-to-rebound-in-new-york.html?_r=0"
        
        let photoData = NSMutableData(contentsOfURL: NSURL(string: urlString)!)
        let dataString = String(data: photoData!, encoding: NSUTF8StringEncoding)
        
        do {
            
            //    <meta property=\"og:image
            
            let regex = try NSRegularExpression(pattern: "<meta.*property=\"og:image\".*content=\"(.*)\".*\\/>", options: .CaseInsensitive)
            let match = regex.firstMatchInString(dataString!, options: .WithoutAnchoringBounds, range: NSRange(location: 0, length: (dataString?.characters.count)!))
            //    regex.matchesInString(dataString!, options: .with, range: <#T##NSRange#>)
            let img = (dataString! as NSString).substringWithRange((match?.range)!)
            
            let httpRange = img.substringFromIndex((img.rangeOfString("http")?.startIndex)!)
            let endRange = httpRange.substringToIndex((httpRange.rangeOfString(" />")?.startIndex)!)
            print(endRange)
            
            let imageD = NSData(contentsOfURL: NSURL(string: endRange)!)
            let image = UIImage(data: imageD!)
        } catch {
            
        }
