我想知道是否有人可以帮我解决我遇到的xml问题。我正在尝试解析这个xml文件:

我遇到的问题是我想获取地图的属性。我可以使用List layernodes = layer.Descendants()来处理图层/ tileset的属性.ToList();和列表tilesetSubNodes = tileset.Descendants()。ToList();但如果我为整个地图做这件事,我会在地图中得到所有内容,这将浪费处理。我尝试在localmap.Descendants(“properties”)中使用var properties = from x选择x;但这也会获得其他属性部分。有没有办法让地图下面的属性组和其他人都没有?如果重要,这就是我目前正在解析文件的方式
