  Regular Expression Format

  Jan 28, 2013 12:16 PM|LINK

  Hi All,

  I've to validate a string with the following criteria using regular expression

  1. Starting with forward slash (/)
  2. No question mark (?)
  3. No dot (.)
  4. No trailing forward slash (/)

  Help on the above is appreciated. Thanks in advance.

  Regards,

  Sachin

  If I understand you correctly - you want to allow strings that begin with a forward slash and contain no periods, question marks or end with a forward slash? If that is the case, then try this : 

  ^[/][^?.]*[^\/.?]$

  (It's off the top of my head so it may need some tweaking but should be close)

  Breakdown

  ^       //Starts Regular Expression
  [/]     //A single forward slash is required
  [^?.]*  //Any number of non period or question mark characters allowed
  [^\/.?] //Cannot end with a forward slash, a period or question mark
  $       //Ends Regular Expression

  Examples
  

  /testing       //Valid
  /test.test/    //Invalid
  /test?test/    //Invalid
  /test?/        //Invalid
  /test          //Valid
  /testtest      //Valid
  /test?         //Invalid
  /test.test     //Invalid
  /test/test     //Valid
  /test?a=b      //Invalid
  test.test      //Invalid
  /test..test    //Invalid
