I'm using the latest version of RichView.
Saving document with footnote/endnote as XML will cause error.

Steps to reproduce:
- Open 'RichViewActions\Demos\DelphiUnicode\ActionTest'
- Add a TRichViewXml (component property values are as following).
- Compile and run, goto Insert -> Insert FootNote (or EndNote), now save the document as xml (code below).
- Error will now happen.

TRichViewXml properties:

Code: Select all

var
  XMLStore: TRichViewXML;
  XMLStore := TRichViewXML.Create(Self);
  XMLStore.DefaultBreakColor := clNone;
  XMLStore.DefaultBreakWidth := 1;
  XMLStore.DefaultParaNo := 0;
  XMLStore.DefaultStyleNo := 0;
  XMLStore.DefaultVAlign := rvvaBaseline;
  XMLStore.Encoding := 'UTF-8';
  XMLStore.InsLoadBackground := False;
  XMLStore.InsLoadPrint := False;
  XMLStore.InsStyleLoadingMode := slmMerge;
  XMLStore.LoadBackground := False;
  XMLStore.LoadPrint := False;
  XMLStore.LoadTagMode := True;
  XMLStore.RichView := RichViewEdit1;
  XMLStore.RootElement := 'rvxml';
  XMLStore.SaveBackground := True;
  XMLStore.SaveImgToFiles := False;
  XMLStore.SavePrint := False;
  XMLStore.SaveSelectionBackground := True;
  XMLStore.SaveSelectionImgToFiles := False;
  XMLStore.SaveSelectionPrint := False;
  XMLStore.SaveSelectionStyles := True;
  XMLStore.SaveLineBreaks := True;
  XMLStore.SaveStyleNames := True;
  XMLStore.SaveStyles := False;
  XMLStore.StyleLoadingMode := slmMerge;
  XMLStore.UseStyleNames := False;
  XMLStore.WantTabs := False;

Code to save as xml:

Code: Select all

procedure TForm3.Saveasxml1Click(Sender: TObject);
var
  fn: string;
begin
  fn := ExtractFilePath(Application.ExeName) + 'text.xml';
  XMLStore.SaveToFile(fn);
end;

Assign SaveLineBreaks property = False.
I'll fix it in the next update.
Actually, this property is not too useful: it saves line breaks in places where text wraps. These line breaks cannot be loaded.
This option does not affect saving true line breaks, they are always saved and loaded.

I tried, it seems fixed the issue now. Thanks!
