Question

I would like to count the number of characters between opening and closing ‘<‘ and ‘>’ for an entire file (e.g. <tag>bla<tag> == 6). I could always write a quick algo to do it, but I am curious to know if there is another way. Maybe Regular expression?

Thanks

You could with regex do it like this:

var brackets = new char[] {'<', '>'};
int counter = 0;
foreach (var match in System.Text.RegularExpressions.Regex.Matches(data, @"</?[^<>]+>"))
  counter += match.ToString().Trim(brackets).TrimStart('/').Length;

This also counts ending tags correctly if you happen to have those aswell.
