Answer 1

After parsing the XML to an XDocument, which I assume you've already been able to do, use the methods below. Note that the GetPath() implementation is fairly naiive. See this answer for a better implementation.

public Dictionary GetLeaves(XDocument doc)
{
    var dict = doc
        .Descendants()
        .Where(e => !e.HasElements)
        .ToDictionary(e => GetPath(e), e.Value);

    return dict;
}

private string GetPath(XElement element)
{
    var nodes = new List();
    var node = element;
    while (node != null)
    {
        nodes.Add(node.Name.ToString());
        node = node.Parent;
    }

    return string.Join("/", Enumerable.Reverse(nodes));
}
