I was wondering if someone could help me out with an xml problem I'm having. I'm trying to parse this xml file:

The problem I'm having is I want to get the properties for the map. I can handle the properties of the layers/tilesets fine using List layernodes = layer.Descendants().ToList(); and List tilesetSubNodes = tileset.Descendants().ToList(); but if i do that for the map as a whole, I get everything within map, which will be wasteful to process. I tried using var properties = from x in localmap.Descendants("properties") select x; but that picks up the other properties sections as well. Is there a way to just get the properties group underneath map and none of the others? If it matters, here's how I'm currently parsing the file

localmap.Element("properties").Elements("property") should work
Descendants includes children, grandchildren, great-grandchildren, etc. I think you want to use Elements("properties").Elements("property").
