Taking a substring from a string

I have a string like 

string str = "<abc> hello </abc> <abc> world </abc>"

Output in List/Array :
hello
world

Now, I want to extract only texts between <abc> and </abc>. There can be n number of abc tags. So I just want the between text.
How can I do that.

I tried using split, but it does not give the between text.

you could split by space then filter out the two expressions you don't want. then add the ones you do to a list.

List<String> list1 = new List<String>();
string str = "<abc> hello </abc> <abc> world </abc>";
string[] array = str.Split(' ');
foreach (string word in array)
{
    if (word != "<abc>" && word != "</abc>")
    {
        list1.Add(word);
    }
}

You can use regular expressions (regex), for example:

string str = "<abc> hello </abc> <abc> world </abc>";
string pattern = "<abc>(.*?)</abc>";

var matches = Regex.Matches(str, pattern);

var result = matches.Cast<Match>().Select(m => m.Groups[1].Value.Trim()).ToArray();

Hope this helps.
