How can I extract a string between <strong> tags usings C#?

Question

Say I have a string such as below:

"Unneeded text <strong>Needed Text</strong> More unneeded text"

How can I extract only the "Needed Text"? I'm guessing Regex is likely the simplest way but Regex still looks like hieroglyphics to me.

Answer 1

Given your example, a simple Split would do it, e.g.

var innerText = text.Split('>')[1].Split('<')[0];

Answer 2

How about using a simple regular expression like:

(?<=<strong>).+?(?=<)

Answer 3

Regex regex = new Regex("<strong>(.*)</strong>");
  var v = regex.Match("Unneeded text <strong>Needed Text</strong> More unneeded text");
  string s = v.Groups[1].ToString();

Answer 4

You don't need regex for that.

You can use String.SubString and String.Split methods like;

string s = "Unneeded text <strong>Needed Text</strong> More unneeded text";
Console.WriteLine(s.Substring(s.IndexOf("<strong>") + "<strong>".Length, s.IndexOf("</strong>") - s.IndexOf("<strong>") - "<strong>".Length));

Output will be;

Needed Text

Here a DEMO.
