replace <select>

I have a string with <select></select> tag. I would like to replace all select tags (with everything in it) with  '______'.

For example "One and  <select><option value="Some text"</option></select> two and
<select><option value="Another text"</option></select>.

This should be come "One and _____ two and _____.
How can I do that?

Here is an option using Regular Expressions:
var rx = new Regex(@"<select>.*?(</select>)", RegexOptions.IgnoreCase | RegexOptions.Singleline);
var s = "One and  <select><option value=\"Some text\"</option></select> two and <select><option value=\"Another text\"</option></select>.";

var replaced = rx.Replace(s, "______");

Console.WriteLine(replaced);

Open in new window


Output:
One and  ______ two and ______.

I hope this helps.

Thank you very much. I used line to simplify.
Actually I would like to replace with different word for each select tag.
I keep the words in an array and there are the same number of items in the array as there are select tags in the string. Do you know how to do this?

Please try the following:
var rx = new Regex(@"<select>.*?(</select>)", RegexOptions.IgnoreCase | RegexOptions.Singleline);
var s = "One and <select><option value=\"Some text\"</option></select> two and <select><option value=\"Another text\"</option></select>.";
var r = new String[]{"*First*", "*Second*"};

var replaced = rx.Replace(s, new MatchReplacements(r).MatchEvaluator);

Console.WriteLine(replaced);

Open in new window

MatchReplacements class:
public class MatchReplacements
{
	private String[] _replacements;
	private int _next;
	
	public MatchEvaluator MatchEvaluator { get; private set; }
	
	public MatchReplacements(String[] replacements)
	{
		_replacements = replacements;
		this.MatchEvaluator = new MatchEvaluator(ReplaceCC);
	}
		
	public string ReplaceCC(Match m)
	{
		return _replacements[_next++];
	}
}

Open in new window

Output:
One and *First* two and *Second*.
