Answer 1

I have changed your XML to make it well formed. Please refer this further in this reply.
Well Formed XML:
<Message>
     <ATO somefiled="X" type="int" value="35"/>
     <FIX somefiled="Y" type="String" value="50"/>
</Message>

what should be done for this ..A simple XPath Query can do trick for you, it can give you ATO or FIX element according to user specified value. XPath query can be:
// replace ##user_specified_value## with value user enters.
String xPathquery= "/Message/child::*[@value='##user_specified_value##']";
