title: Regex Pattern Matching: Using only the start and end of a pattern for matching
body: <p>Hi I am really struggling with this problem; </p>
  
  <p>I am trying to use regex to match the start and end of a pattern where the middle of the pattern can change. So I would like to use a regex expression that will match the start which is constant and the end which is constant can anyone help? </p>
  
  <p>For instance the start of the pattern is "/>" and ends with "abc"</p>
  
  <p>I am using c#.</p>
  
  <p>Thanks</p>
