Soluzione
You should take a focus on XReplaceable interface. Here is the example. Please note, that there's no error handling. I've tested it with LibreOffice writer and it works fine for me.
uses
ComObj;
procedure OpenOfficeReplace(const AFileURL: string; ASearch: string; const AReplace: string);
var
StarOffice: Variant;
StarDesktop: Variant;
StarDocument: Variant;
FileReplace: Variant;
FileParams: Variant;
FileProperty: Variant;
begin
StarOffice := CreateOleObject('com.sun.star.ServiceManager');
StarDesktop := StarOffice.CreateInstance('com.sun.star.frame.Desktop');
FileParams := VarArrayCreate([0, 0], varVariant);
FileProperty := StarOffice.Bridge_GetStruct('com.sun.star.beans.PropertyValue');
FileProperty.Name := 'Hidden';
FileProperty.Value := False;
FileParams[0] := FileProperty;
StarDocument := StarDesktop.LoadComponentFromURL(AFileURL, '_blank', 0, FileParams);
FileReplace := StarDocument.CreateReplaceDescriptor;
FileReplace.SearchCaseSensitive := False;
FileReplace.SetSearchString(ASearch);
FileReplace.SetReplaceString(AReplace);
StarDocument.ReplaceAll(FileReplace);
ShowMessage('Replace has been finished');
StarDocument.Close(True);
StarDesktop.Terminate;
StarOffice := Unassigned;
end;
And the usage of the example
procedure TForm1.Button1Click(Sender: TObject);
begin
OpenOfficeReplace('file:///C:/File.odt', 'Search', 'Replace');
end;
There are also several search/replace options for SearchDescriptor.
