{
    foreach (var checkBox in node.Tags.OfType<CheckBox>())
    {

var report = new Document();
foreach (var page in oneFile)
{
    if (page.GetChildNodes<ITaggable>().Any(e => e.Tags.OfType<CheckBox>().Any(x => !x.Checked && DateTime.UtcNow.Subtract(TimeSpan.FromDays(7)) <= x.CreationTime)))
    {
        report.AppendChildLast(page.Clone());
    }

var report = new Document();
var endOfWeek = DateTime.Today.AddDays(5 - (int)DateTime.Today.DayOfWeek);
foreach (var page in oneFile)
{
    if (page.GetChildNodes<ITaggable>().Any(e => e.Tags.OfType<NoteTask>().Any(x => !x.Checked && DateTime.UtcNow.Subtract(TimeSpan.FromDays(7)) <= x.CreationTime && x.DueDate <= endOfWeek)))
