Parse a string which is HTML input

Question

Is there an elegant way to get lat and lon values from this string using C#? Thanks. String is like this :

<input type="hidden" name="myinput" id="myinput" value='{"lat":11.111111,"lon":22.222222}'>

Depends on your definition of elegant. Immediately my first though is just use a Regex. — Brandon, Nov 18 '16 at 14:42

@Steve Sure. He's not matching tags though. He could overkill the everliving out of it and use a parser as mentioned in your link. 6 in one..... — Brandon, Nov 18 '16 at 14:46
Try HtmlAgilityPack, see this SO link [HtmlAgilityPack](http://stackoverflow.com/questions/846994/how-to-use-html-agility-pack) — Steve, Nov 18 '16 at 15:02

Per my comment, this is how I'd do it. I'm not claiming to be awesome at Regex by any means. There's probably a better way.

var r = new Regex(@"""lat"":(?<lat>\d+\.\d+),""lon"":(?<lon>\d+\.\d+)");
var m = r.Match(@"<input type=""hidden"" name=""myinput"" id=""myinput"" value='{""lat"":11.111111,""lon"":22.222222}'>");
if ( m.Success )
{
    Console.WriteLine(f.Groups["lat"]);
    Console.WriteLine(f.Groups["lon"]);
}
