Question

i have a simple regex expression below to pull out the value within a string that is surrounded by end**end, example below. However, although it’s stupidly simple im struggling to get the results I need! Is there something obvious I’m missing!
Many thanks as always.

var str = "endhelloend";
var match = Regex.Match(str, @"end([a-z]+)end$", RegexOptions.IgnoreCase);

if(match.Success)
{
    result = match.Groups[0].Value  // should return 'hello'
}

Use solution 1 to extract .html text content and then filter your desired text from text by using solution 2.

1. To clean html elements within .htm file, try this:

   string CleanXml(string DirtyXml)
   {
       //string clean = ""; 
       int startloc = 0, endloc = 0;
   
       for (int x = 0; x <= DirtyXml.Length-1; x++)
       {
           if (DirtyXml[x] == '<')
           {
               startloc = x;
               x++;
           }
           if (DirtyXml[x] == '>')
           {
               endloc = x;
               x++;
               DirtyXml = DirtyXml.Remove(startloc, (endloc - startloc)+1);
               x = 0;
           }   
       }
       return DirtyXml;
   }
   

2. Regex to filter text “endhelloend” to obtain “hello”
   

       string result = "";
       var str = "endhelloend";
       var match = Regex.Match(str, @"end([a-z]+)end$", RegexOptions.IgnoreCase);
       if(match.Success)
       {
           result = match.Groups[1].Value;  // Returns 'hello'
       }
       Console.WriteLine(result);
       Console.ReadLine();
