#20 NativeXML memory leak. Method WriteToString.

[Yuri Serebrennikov]

The method TXmlNode.WriteToString contains a memory leak

function TXmlNode.WriteToString: Utf8String;
var
SS: TsdStringStream;
begin
SS := TsdStringStream.Create('');
WriteStream(SS);
Result := SS.DataString;
end;

It is necessary to release TsdStringStream

function TXmlNode.WriteToString: Utf8String;
var
SS: TsdStringStream;
begin
SS := TsdStringStream.Create('');
WriteStream(SS);
Result := SS.DataString;
FreeAndNil(SS);
end;
