           string str1 = "<div class=" + str + ">" + "(101) 1010-1234" + "</div>";

           string str2 = "<div class=\"phone-number\"><\\(\\d{3}\\) \\d{3}\\-\\d{4}/div>";

Ahem:

C#

string str1 = "<div class=" + str + ">" + "(101) 1010-1234" + "</div>";
string str2 = "<div class=\"phone-number\"><\\(\\d{3}\\) \\d{3}\\-\\d{4}/div>";

Look closely:

\\d{3}\\-\\d{4}

Is three digits, followed by a hyphen, followed by four digits.

1010-1234

Is four digits, followed by a hyphen, followed by four digits.
