Move bookmarks between levels

Aspose.PDF Product Family
1

Hi,

I have pdf with following (sample) bookmarks:

Bookmark1.1
Bookmark1.2
Bookmark1.3
Bookmark2.1
Bookmark2.2

I’d like to process those bookmakrs to have following structure:

TopLevelBookmark1
Bookmark1.1
Bookmark1.2
Bookmark1.3
TopLevelBookmark2
Bookmark2.1
Bookmark2.2

I was trying with such a code:

var doc = new Aspose.Pdf.Document(memoryStream);
var previousBookmarks = doc.Outlines.Cast().ToList();
//get bookmarks for each level
var sub = previousBookmarks.Where(b => b.Title.StartsWith(“Bookmark1.”)).ToList();
var sub2 = previousBookmarks.Where(b => b.Title.StartsWith(“Bookmark2.”)).ToList();

//delete previous bookmarks
doc.Outlines.Delete();

//new top level bookmark
var newTopLevel = new OutlineItemCollection(doc.Outlines);
newTopLevel.Title=“TopLevelBookmark1”;
newTopLevel.Action = sub.First().Action; //set top level bookmark destination to be the same as dest of first child
sub.ForEach(newTopLevel.Add);
doc.Outlines.Add(newTopLevel);

//second top level bookmark
var newTopLevel2 = new OutlineItemCollection(doc.Outlines);
newTopLevel2.Title=“TopLevelBookmark2”;
newTopLevel2.Action = sub.First().Action;
sub.ForEach(newTopLevel2.Add);
doc.Outlines.Add(newTopLevel2);

doc.Save(<some_path_to_save>);

Unfortunatelly final outcome looks like:
TopLevelBookmark1
Bookmark1.1
Bookmark1.2
Bookmark1.3
Bookmark2.1
Bookmark2.2
TopLevelBookmark2
Bookmark2.1
Bookmark2.2

I’ve tested also with different subsets of previousBookmarks collection, and it’s weird for me that when I even add only sub.Take(1) to the newMain collection, it adds all bookmarks as children to the TopLevelBookmark1.
