REST webservice that consumes XML

I am learning REST webservice and confused about some concepts. I want to create a RESTful webservice that consumes an XML like:

<?xml version="1.0" encoding="UTF-8"?>
<emp:EmployeeEntry xmlns:emp="http://ift.tt/1sKyPs7">
  <emp:number>12345</emp:number>
  <emp:name>George</emp:name>
  <emp:date>2015-04-03</emp:date>
  <emp:address>
    <emp:city>Paris</emp:city>
    <emp:street>East 35</emp:street>
  </emp:address>
</emp:EmployeeEntry>

So, If I want to create a restful webservice that consumes this XML, How would be the signature of my method?

    public creatEmp(XML xml);   

Should it be like this? (Because I saw some examples of methods that consume XML, but they are taking parameter as main entiry object eg; Employee I don't understand how a method that consumes XML accepts and Entity object as parameter)

Also, If the method is given XML as parameter, do I have to implement parsing logic in the method then create Employee object from that and the start the main create logic?

I have some knowledge gaps, please suggest me some examples or some good tutorials.
