Using regex to retrieve text between multiple HTML tags

Using a regex, I want to be able to get text between multiple DIV tags. For example, the following:

<div>first html tag</div>
<div>another tag</div>

Output:

first html tag
another tag

I use the regex pattern only for my last div tag and skip the first. The code:

    static void Main(string[] args)
    {
        string input = "<div>This is a test</div><div class=\"something\">This is ANOTHER test</div>";
        string pattern = "(<div.*>)(.*)(<\\/div>)";

        MatchCollection matches = Regex.Matches(input, pattern);
        Console.WriteLine("Matches found: {0}", matches.Count);

        if (matches.Count > 0)
            foreach (Match m in matches)
                Console.WriteLine("Inner DIV: {0}", m.Groups[2]);

        Console.ReadLine();
    }

Conclusion:

Matches found: 1

Internal DIV: this is ANOTHER test

Replace the template with an incorrect match

static void Main(string[] args)
{
    string input = "<div>This is a test</div><div class=\"something\">This is ANOTHER test</div>";
    string pattern = "<div.*?>(.*?)<\\/div>";

    MatchCollection matches = Regex.Matches(input, pattern);
    Console.WriteLine("Matches found: {0}", matches.Count);

    if (matches.Count > 0)
        foreach (Match m in matches)
            Console.WriteLine("Inner DIV: {0}", m.Groups[1]);

    Console.ReadLine();
}

Since the other guys didn't mention HTML tags with attributes, here is my solution to solve this problem:

// <TAG(.*?)>(.*?)</TAG>
// Example
var regex = new System.Text.RegularExpressions.Regex("<h1(.*?)>(.*?)</h1>");
var m = regex.Match("Hello <h1 style='color: red;'>World</h1> !!");
Console.Write(m.Groups[2].Value); // will print -> World

-, :

((<div.*>)(.*)(<\\/div>))+ //This Regex will look for any amount of div tags, but it must see at least one div tag.

((<div.*>)(.*)(<\\/div>))* //This regex will look for any amount of div tags, and it will not complain if there are no results at all.
