Retrieve Xml elements using c#

Hi

How to retrieve the "SampleName","1234","07-07-1977" from the below xml document. I tried loading that into xmldocument and loop but realized that is not efficient as the actual document has many elements.

<?xml version="1.0" encoding="utf-8" ?>
<fC xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.test.com">
  - <fF>
    - <f d:name="a1" xmlns:d="http://www.test.com">
      <d:text>Medha</d:text>
      <d:restriction>REQUIRED</d:restriction>
    </f>
    - <f d:name="a2" xmlns:d="http://www.test.com">
      <d:text>11111</d:text>
      <d:restriction>REQUIRED</d:restriction>
    </f>
    - <f d:name="a3" xmlns:d="http://www.test.com">
      <d:date>07-07-1999</d:date>
      <d:restriction>REQUIRED</d:restriction>
    </f>    
  </fF>
</fC>

Please suggest any resources or sample code.
Thank You
