C# parsing .XSPF (XML)

Question

i have a playlist that i need to parse.

 but i dont know how i could get the "title"(folder) and "tid"(id) so that i would have them in groups  like this :

BillyJ  0,1,2,3,4,5,6...

Solo 60,61,62,63,64..

Best 105,106,107

 

here is the .xspf 

    <?xml version="1.0" encoding="UTF-8"?>
    <playlist xmlns="http://xspf.org/ns/0/" xmlns:vlc="http://www.videolan.org/vlc/playlist/ns/0/" version="1">
        <title>Playlist</title>
        <trackList>
            <track>
                <location>file:///E:/Downloads/video1.mp4</location>

            <vlc:item tid="111" />
        </vlc:node>
        </vlc:node>
</extension>
</playlist>

 i have parsed the first part of the file the "location" "duration" and " id".

But yeah like i said im stuck and dont know how i would do it . i can get all the titles and all the tids but they need to be grouped(nested)  like in the playlist
