Example

The following example demonstrates how to use the RegExpr.Compile method to force expression conversion and to get conversion errors that occur during compilation.

DelphiScript

procedure CompileSample;
var
  MyRegExp: OleVariant;
  Mes: string;
  Err, Pos: integer;
begin

  MyRegExp:=HISUtils.RegExpr;
  try
    // Specifies a regular expression
    MyRegExp.Expression := '[]';
    // Forces expression conversion
    MyRegExp.Compile;
    // Performs operations over text
    …
  except
    // If a compilation error occurs…
    // Obtains the code of the occurred error
    Err := MyRegExp.LastError;
    // Obtains the description of the occurred error
    Mes := MyRegExp.ErrorMsg[Err];
    // Obtains the position, in the regular expression, where the error occurred
    Pos := MyRegExp.CompilerErrorPos;
    // Posts information on the error to the test log
    Log.Error('Error: ' + aqConvert.IntToStr(Err) + ' ' + Mes + ' (pos ' + aqConvert.IntToStr(Pos) + ')');
  end;
end;
