What have you tried? There are plenty of resources on the net helping you write Regex and even testing on your own text...if your list of tags is limited to two, any reason you want to waste time writing Regex instead of String.Replacing the whole thing?

mayank.bhuvnesh 10-Mar-15 7:06am

There may be any number of occurrences. Suppose there are two. 
I am trying <ins.*/ins> to replace but it checks the <ins> for first occurrence and </ins>for last occurrence removing all the table data between these. Same case is with script tag.

This says find < ins then take any number of other chars in between until you find ins > and replacae them :) The solution below seems alright.

Hi,

You can try this:

C#

var regex = new Regex(
   "(\\<script(.+?)\\</script\\>)|(\\<ins(.+?)\\>)", 
   RegexOptions.Singleline | RegexOptions.IgnoreCase
);

string ouput = regex.Replace(yourString, "");

This worked for me. Hope this helps !! :) :)

This is how I did:

System.Net.WebClient wc = new System.Net.WebClient();
System.IO.Stream stream = wc.OpenRead("C:/Test.html");
System.IO.StreamReader reader = new System.IO.StreamReader(stream);
string str = reader.ReadToEnd();

var regex = new Regex(
"(\\<script(.+?)\\</script\\>)|(\\<ins(.+?)\\>)",
RegexOptions.Singleline | RegexOptions.IgnoreCase
);

string ouput = regex.Replace(str, "");

This is working for me
