title: how to recognize paragraph in a text by regular expression?
body: <p>I'm writing a software that converts Text to HTML and also I use the regular expression. I wanna know how to identify paragraph in the body of text?
  I wrote a snippet of code for identifying paragraph, for example, in this text, it just identifies "my" word.To identify a paragraph, I look for text that has double spaces before and after it.</p>
  
  <blockquote>
    <p>Hi  </p>
    
    <p>my name is radamal shera.</p>
  </blockquote>
  
  <pre><code>   private void btnConvert_Click(object sender, EventArgs e)
      {
  
  
          string inputText = txtInput.Text;   
  
  
         string pattern = @"(\r\n)([a-zA-Z]+)";
  
          Match result = Regex.Match(txtInput.Text, pattern);
          if (result.Success)
          {
              Debug.WriteLine("match : {0}", result.Value);
          }
  
  
      }
  </code></pre>
