I just tried to your code with the XML provided in your file, and it worked for 
me. A System.out.println(retVal) gave me the metadata content. I also tried an 
arbitrary attribute:

         System.out.println(retVal.getOrganisationName());

which worked as expected for me. I'm not sure which object you wanted to compare 
with the "equals" method? Most metadata method returns InternationalString 
object, not String, even if they look the same when printed with System.out. 
Consequently the following will never work:

     if (retVal.getOrganisationName().equals("NOAA"))

You need to use instead:

     if (retVal.getOrganisationName().toString().equals("NOAA"))

(Of course a real application needs to check for null values first).

Is it the kind of equality tests you wanted to perform?
