Sure.

If you're wanting to deal with the actual attributes of
specific tags, you could use the OnAttribute event..

procedure TForm1.ATagParser1Attribute(Sender: TObject;
Attribute: TAttributeElement; var Abort: Boolean);
var
TagIndex, AttrIndex: Integer;
begin
TagIndex := FindTagID(Attribute.ParentTagHash);
Case TagIndex Of
TID_TABLE :
Begin
AttrIndex := FindAttributeID(Attribute.Hash);
Case AttrIndex Of
AID_FACE :
// Attribute.Value = font name
AID_SIZE :
// Attribute.Value = font size
End;
End;
End;
end;

Hope this helps..
