C#

Hi,

I need a help regarding cache.
I am making a database call which is returning an XML. Take example as below

<root>
  <Emp id="m1" text="Test1" />
  <Emp id="m2" text="Test2">
    <Emp id="m2-1" text="Test3">
      <Emp id="m2-11" text="Test4" />
      <Emp id="m2-12" text="Test5" />
      <Emp id="m2-13" text="Test6" />
      <Emp id="m2-14" text="Test7" />
    </Emp >
</root>

I want to cache all the data from XML and while retrieving the data i want to retrieve on the basis of "id". for example I need text of id "m2-1".

Please help me on how to cache the data and retrieve it in c#.

Thanks in advance
