Help a noob parse an xml file

I didn't really want to put this here but I really don't understand all of this. I understand xml, but parsing it in C# is the problem. I searched on unity forums and answers but the almost all the solutions I found were either outdated or I didn't understood a single line of the code.

In my game I have a 5x5 grid, blue, green and grey blocks. The blocks are placed on the grid according to my xml file. This is an example of level 40: (0 means no block, 1 means a grey block, 2 means a blue block and 3 means a green block)

 <levels>
 <level id="40">
    <row id="1">
       <col id="1">1</col>
       <col id="2">0</col>
       <col id="3">0</col>
       <col id="4">0</col>
       <col id="5">3</col>
    </row>
    <row id="2">
       <col id="1">3</col>
       <col id="2">0</col>
       <col id="3">1</col>
       <col id="4">0</col>
       <col id="5">2</col>
    </row>
    <row id="3">
       <col id="1">2</col>
       <col id="2">0</col>
       <col id="3">0</col>
       <col id="4">1</col>
       <col id="5">0</col>
    </row>
    <row id="4">
       <col id="1">0</col>
       <col id="2">0</col>
       <col id="3">1</col>
       <col id="4">0</col>
       <col id="5">0</col>
    </row>
    <row id="5">
       <col id="1">0</col>
       <col id="2">1</col>
       <col id="3">0</col>
       <col id="4">0</col>
       <col id="5">0</col>
    </row>
 </level>
 </levels>

I will have a script that loops through the rows and columns given in the file to place the right blocks in the right place. But first I need to know how the script will select the right level and columns also with the id="" parameter. Making a loop shouldn't be that big of a problem for me but parsing the data is.

I really hope someone can help me on this. Thanks in advance.
