Open RSS channel

[volod3000]

Hi,

Try to view the rss-channel in RichView, through RichViewXML, but always a mistake
(No root element.) and in RichView empty

That's part of the code:

Code: Select all

var rssUrl: String = 'http://112.ua/rss';

procedure TForm1.Button2Click(Sender: TObject);
var
   RssXml: String;
   Stream: TFileStream;
   f: TextFile;

begin
    RichViewEdit1.Clear;
    AssignFile (f, 'myxml.txt');
    Rewrite (f);

      IdHTTP1.HandleRedirects := true;
      IdHTTP1.ReadTimeout := 5000;
      IdHTTP1.Request.ContentEncoding := 'UTF-8';
    cli:= 2;
  try
      RssXml := IdHTTP1.Get(rssUrl);
  except
    on E: Exception do
    begin
      ShowMessage ('Error: ' + E.Message);
      Exit;
    end;
  end;

     WriteLn (f, RssXml);
     CloseFile (f);
  try
    try
     Stream := TFileStream.Create('myxml.txt', fmOpenRead);//properties.xml
     Stream.Position:= 0;
    except
     ShowMessage('Файл не может быть загружен.');
     Exit;
    end;


     RichViewXML1.RootElement:= 'channel';

     RichViewXML1.LoadFromStream(Stream);
     RichViewEdit1.Format;

  finally
     Stream.Free;
  end;

end;

procedure TForm1.RichViewEdit1Jump(Sender: TObject; id: Integer);
var 
      ItemNo: Integer;
      RVData: TCustomRVFormattedData;
      s: String;
      Tag: string;

begin

  RichViewEdit1.GetJumpPointLocation(id, RVData, ItemNo);
  Tag := RVData.GetItemTag(ItemNo);
  RichViewXML1.LoadFromFile(RichViewXML1.BaseFilePath +Tag + '.xml');
  RichViewEdit1.Format;
end;

That's part of the code xml

Code: Select all

Do not scold much, I'm just learning.
Where the error, please tell me.
