Question

I have a HTML file having GPS coordinates which I want to extract, I am trying to do this by creating a regEx but so far had no luck.

I am using C# to parse the HTML file

Here’s the sample GPS Data that should be extracted.

S 33 58.254 E 023 53.269

any help would be appreciated.

This is the Sample Text in which GPS coordinates are specified

<span style="text-decoration: underline;">TOURIST INFORMATION</span><br>
Tourism Office <span style="font-style: italic;">(S 33 58.254 E 023
53.269, Gammasi St, 042-281-1098,)

and I need to only extract out S 33 58.254 E 023 53.269

Answer 1

Here is an example in C#, just in case you want to parse the GPS, and not only extract it from the HTML code:

var text = @"Some example that contains S 33 58.254 E 023 53.269 
                  and also S 22 58.123 W 021 53.2";
var pattern = @"([SN])\s(\d+)\s(\d+(?:\.\d+)?)\s([EW])\s(\d+)\s(\d+(?:\.\d*)?)";
var m = Regex.Matches(text, pattern);
for (int i = 0; i < m.Count; i++) {
    Console.WriteLine("GPS Found: {0}", m[i].Value);
    Console.WriteLine("-----");
    Console.WriteLine(m[i].Groups[1].Value);
    Console.WriteLine(m[i].Groups[2].Value);
    Console.WriteLine(m[i].Groups[3].Value);
    Console.WriteLine(m[i].Groups[4].Value);
    Console.WriteLine(m[i].Groups[5].Value);
    Console.WriteLine(m[i].Groups[6].Value);
    Console.WriteLine("-----");
}

The above example will print:

GPS Found: S 33 58.254 E 023 53.269  
-----  
S  
33  
58.254  
E  
023  
53.269  
-----  
GPS Found: S 22 58.123 W 021 53.2  
-----  
S  
22  
58.123  
W  
021  
53.2  
-----  

Edit:
I don’t really know if values like 53.2 could be integers, like 53, but I had that in count just in case.
