Need suggestion on creating Base Class Library

I'm still learning C#..I'm developing an academic project to pick the players for a team from the pool of available players. The players database will be given in an xml file will be something like this.

xml version="1.0"?> 

<team> 
<club>MyTeamclub> 


<player name="kaka"> 
<type>Center Forwardtype>
<other_playing_positions>Midfielderother_playing_positions>
<other_playing_positions>Right Wingother_playing_positions> 
<cannot_play_as> 
<defender>center backdefender> 
<defender>right backdefender> 
cannot_play_as> 
<height>181height> 
<rating>92rating> 
player> 

<player name="rooney"> 
<type>Strikertype> 
<other_playing_positions>Center Forwardother_playing_positions> 
<other_playing_positions>Attacking Midfielderother_playing_positions> 
<cannot_play_as> 
<defender>center backdefender> 
<defender>keeperdefender> 
cannot_play_as> 
<height>181height> 
<rating>92rating> 
<penalty>specialistpenalty>

I'm planning to develop a BCL for creating an array of objects by 
reading this xml file; with each object representing each player. So 
that if I'm a coach, I can pick the player according to my wish. Please 
give me any suggestions on this project.Any help in reading xml is also
appreciated.

To do this what all I need to learn?
-reading XML
-developing .net components (BCL)
-what concepts in particular in C#?
