wahoyaho Posted November 25, 2007 Posted November 25, 2007 (edited) How can I make it check that there's only 1 of a certain character and removes all the rest? So for example if only one character "a" is allowed a string of test1atest2atest3 would become test1atest2test3 Edited November 27, 2007 by wahoyaho
picaxe Posted November 27, 2007 Posted November 27, 2007 Not using regexp, but this will do it $string = "test1atest2atest3" $find = "a" $first = StringInStr($string, $find) If $first > 0 Then $result = StringReplace($string, $find, "") $result = StringLeft($result, $first - 1) & $find & StringRight($result, StringLen($result) - $first + 1) MsgBox(0, "", $result) EndIf
