Reading XML in C# or VB

I am tring to read the iTunes Music Library XML in my application however i have no idea on how to do this, what i'm trying to do is to search for a specific track name a specing key, for example "Artist", "Album" etc.. yes, i know how to use iTunes COM but there are some track information that cannot be access through it such as if the Track is "Explicit" there is an additional key

<key>Explicit</key><true/>

what i want to do is search for a specific track name and check if it track has an explicit key.

I found this on the web:

    Dim itunesLib As XElement = XElement.Load("xmllocation")

    Dim itunesPlaylists = From key In itunesLib...<key> Where key.Value = "Name"
                          Select key.ElementsAfterSelf("string").Value

    List1.ItemsSource = itunesPlaylists

but it only list all my tracks in a listbox, can anyone please help me.
