asp.net - How to get the string from html file?

Question

How should I search for and get a string from html files using c# in asp.net? This is the code:

 private string getHtml(string key)
 {
     StreamReader f = new StreamReader("path");
     string htmlTag = key;
     string str = f.ReadToEnd().ToString();
     Match m = Regex.Match(str, "<" + htmlTag + ">" + "(.*)" + "</" +   
                                htmlTag + ">", RegexOptions.Singleline);
     Console.WriteLine(m.Groups[0]);             
     return str;
 }

Answer 1

In your RegEx, try changing this:

"(.*)"

to this:

"([^<]*)"

So, instead of matching ANY character, you match any characters up to (but not including) the next less-than symbol.

You might also want to change this:

"</" + htmlTag + ">"

to this

"</ ?" + htmlTag + ">"

To allow for a space after the slash (you can ignore this second suggestion if you have full control over the HTML documents and know exactly how they were coded)
