Hi to all,

I'm using regular expressions!

Here is the sample code from the xharbour.com help file:

Code: Select all | Expand

// The example extracts an eMail address from a text string.
// The search is case insensitive although the RegEx defines
// character classes only with upper case letters.

   PROCEDURE Main
      LOCAL cRegEx := "[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}"
      LOCAL cText  := "Send your request to info@xharbour.com " + ;
                      "for more information"
      LOCAL cEmail, nStart, nLen

      cEmail := HB_AtX( cRegEx, cText, .F., @nStart, @nLen )

      ? cEmail        // result: info@xharbour.com
      ? nStart        // result: 22
      ? nLen          // result: 17
   RETURN
