accept a xml in web api

Hi all, 

I have a xml file like belowm 

<?xml version="1.0" encoding="UTF-8"?>

<bookstore>

  <book category="cooking">

    <title lang="en">Everyday Italian</title>
    <author>Giada De Laurentiis</author>
    <year>2005</year>
    <price>30.00</price>
  </book>

</bookstore>

and i wanted to create a web api end point to accept the above xml and save it in a local drive as a xml file.   also if i can do some validation on xml beofore I accept this in web api side that would be really great, 

could some one direct me in to the right approach to do this ? 

thanks
