  using variables inside of a regular expression

  Jul 29, 2004 02:48 PM|LINK

  Hi, I am new to regular expressions. I am looking through .cs files to try and find a pattern. I am trying to find all instances of returning a variable that might be created on the local stack: my function { variable = something; ... return variable } I don't want to use C# or any language. I want to find all occurences using just a regular expression. I have not found any examples of using the variable inside the regular expression. All the examples show the code getting the value of the variable. I don't want that. Can you help me?

  I assume it would be easier to make a search for all returns with a grouping reference given to their function. After they're all found, turn around and and search the function for a declaration of the var (noting of course inheritance and interface implementations). This can be extremely tricky for many reasons. Namely you might have something like this:

  string fubar ( )
  {
      string strTemp = "xwz";
  
  
      return strTemp.Replace("w", "y");
  }

  Do you count that? Technically, you're returning something else (new memory location when dealing with a string manipulation).
