Question

Im writing an app which reads an RSS feed and places items on a map.
I need to read the lat and long numbers only from this string:
http://www.digitalvision.se/feed.aspx?isAlert=true&lat=53.647351&lon=-1.933506
.This is contained in link tags

Im a bit of a programming noob but im writing this in C#/Silverlight using Linq to XML.

Shold this text be extrated when parsing or after parsing and sent to a class to do this?
Many thanks for your assistance.

EDIT. Im going to try and do a regex on this

this is where I need to integrate the regex somewhere in this code. I need to take the lat and long from the Link element and seperate it into two variables I can use (the results are part of a foreach loop that creates a list.)

  var events = from ev in document.Descendants("item")
                     select new
                     {
                         Title = (ev.Element("title").Value),
                         Description = (ev.Element("description").Value),
                         Link = (ev.Element("link").Value),
                     };

Question is im not quite sure where to put the regex (once I work out how to use the regex properly! 🙂 )

Answer 1

try this

var url = "http://www.xxxxxxxxxxxxxx.co.uk/map.aspx?isTrafficAlert=true&lat=53.647351&lon=-1.93350";
var items = url.Split('?')[1]
    .Split('&')
    .Select(i => i.Split('='))
    .ToDictionary(o => o[0], o => o[1]);
var lon = items["lon"];
var lat = items["lat"];
