c# Regex on XML string handler
- by Dan Sewell
Hi guys. Trying to fiddle around with regex here, my first attempt.
Im trying to extract some figures out of content from an XML tag. The content looks like this:
www.blahblah.se/maps.aspx?isAlert=true&lat=51.958855252721&lon=-0.517657021473527
I need to extract the lat and long numerical vales out of each link. They will always be the same amount of characters, and the lon may or may not have a "-" sign.
I thought about doing something like this below: (The string in question is in the "link" tag):
var document = XDocument.Load(e.Result);
if (document.Root == null)
return;
var events = from ev in document.Descendants("item1")
select new
{
Title = (ev.Element("title").Value),
Latitude = Regex.xxxxxxx(ev.Element("link").Value, @"lat=(?<Lat>[+-]?\d*\.\d*)", String.Empty),
Longitude = Convert.ToDouble(ev.Element("link").Value),
};
foreach (var ev in events)
{
do stuff
}
Many thanks!
