How to replace a elements in a KML file?

[vividos]

I'd like to use SharpKml to scan a kml file for NetworkLink elements and replace them with their (current) downloadable content. For this I check all elements (using kml.Root.Flatten() if they are NetworkLink elements, get their URL and download the kml content. I parse that text and get another KmlFile object. Then I generate a new Folder object, clone and copy all features from the loaded KmlFile's Document in that new folder and try to replace the NetworkLink with that. I couldn't figure out that last part, though. My code looks mostly like this:

Kml insertKml = LoadKmlFromText(kmlToInsert);
var doc = insertKml.Feature as Document;

var folder = new Folder
{
    Name = doc.Name
};

foreach (var featureToInsert in doc.Features)
    folder.AddFeature(featureToInsert.Clone());

networkLink.Parent.AddChild(folder);
networkLink.Parent.RemoveChild(networkLink);

How is that supposed to work? Is it possible at all? Thanks!

It looks like you're on the right path. Since the parent of the NetworkLink is a Container, you might be best using the methods on that type:

var container = (Container)networkLink.Parent;
container.AddFeature(folder);
container.RemoveFeature(networkLink.Id)

Hope that helps

Thanks, that worked! I had to check if it's really a Container or the Kml element (when the NetworkLink is the only and topmost element), but that works. I also had to do a workaround when networkLink.Id is null; I generated a temporary Guid that's then used to remove the feature again.
