Using Linq To XML, method to get path to all leaves?

Question

Ok, I\'ve got the following XML tree

    
        
            1000         


        

Answer 1

You can find the leaves by looking for elements that have no descendants:

var doc = XDocument.Load(fileName);
var leaves = 
    from e in doc.Descendants()
    where !e.Elements().Any()
    select e;

I don't know if there is a built-in way to get the path of an element, but you can easily create an extension method to build it:

static class Extensions
{
    public static string Path(this XElement element)
    {
        XElement tmp = element;
        string path = string.Empty;
        while (tmp != null)
        {
            path = "/" + tmp.Name + path;
            tmp = tmp.Parent;
        }
        return path;
    }
}

You can then build the dictionary like this:

var dict = leaves.ToDictionary(e => e.Path(), e => e.Value);
