Всем здравствуйте!
Подскажите как извлечь "8 Марта" из класса "second_class"

Procedure TMainForm.Button1Click(Sender: TObject);
Var
  html, ClassNameStr: String;
  i: Integer;
  Element: IHTMLElement;
  idoc: IHTMLDocument2;
  V: OleVariant;
Begin
  html :=
    '<div class="first_class">Вчера</div>  <time class="second_class" datetime="2020-02-20">8 марта</time>';
  V := VarArrayCreate([0, 0], varVariant);
  V[0] := html;
  idoc := CoHTMLDocument.Create As IHTMLDocument2;
  idoc.write(PSafeArray(System.TVarData(V).VArray));
  For i := 0 To idoc.all.length - 1 Do
  Begin
    Element := idoc.all.item(i, 0) As IHTMLElement;
    ClassNameStr := Element._className;
    If Element._className = 'first_class' Then
    Begin
      Label1.Text := Element.innerText;
    End;
    If Element._className = 'second_class' Then
    Begin
      Label2.Text := Element.innerText;
    End;
  End;
End;
