XML Parser Using C Language

It took me forever to understand this question, I finally got it but I still have some troubles. As the topic says, I need to parse XML file into .txt file using C language.

For example:

 <?xml version="1.0" encoding="UTF-8"?>
   <breakfast_menu>
     <food>
      <name>Belgian Waffles</name>
        <price>$5.95</price>
            <description>
           Two of our famous Belgian Waffles 
           with plenty of real maple syrup
            </description>
          <calories>650</calories>
    </food>

It will look like this in the text file :

  Item #1: Food
  name: Belgian Waffles
  price: $5.95
 description: Two of our famous 
 Belgian Waffle with plenty of real 
 maple syrup
 calories: 650

Can someone puts me in the right path to start. Also I'll be thankful if you provide me with links that explain how parser works using c language

Thank you!
