Issue Details

  • I have a string that I am working with where I need to extract a substring.  The full string has slashes in it because it is a file path.  How can I extract a substring up to a given folder or directory?
  • I have a string with typed out special characters such as \r, \t, and \n.  I am trying to match those special characters.  How can I match a character pair that includes a slash (\) ?

Solution

In order to match a pattern that includes the backslash character (\) or other special symbols or characters, you will want to look at the Special Characters for Match Pattern help page for how to work with each special character.  Specifically for backslashes, you will need to escape the backslash first, meaning to match the string \r, you will need to put in the pattern as \\r.  If you only put in \r, you will end up matching for the non-print carriage return that is represented by \r.
