Retrieve tag and value in xml with scripting

Hi,

Please find xml structure from which I am trying retrieve the tag and its value.

TValue.xml

<A>

     <A.1>

          <A.2>

               <A.3/>

               <A.4>Test<A.4>

           <B>

          <C>

          <D>

I need to retrieve A.4(tag name) and its value(Test). I used

Inputs.GetChild(0).GetChild(0).GetProperty("A.4") and GetValue("A.4") to retrieve tag and values. I am not able to retrieve these all the time.

Thank you.

Regards

Deepu
