can I just specify first_child of any element within the root?
first_child ($optional_condition)

Return the first child of the element, or the first child matching the $optional_condition

for e.g., given below xml, in order to get to <getthis value="found" />, do I always have to go

       if ($one->first_child('traffic')->first_child('something')->fir
+st_child('somethingelse')->first_child('getthis')->att('value') eq 'f
+ound') {
                         push @ids, $one->att('id');
                         push @ids, $one->true('yes');
        }

OR can I just pick the element like

       if ($one->first_child('getthis')->att('value') eq 'found') {
                         push @ids, $one->att('id');
                         push @ids, $one->true('yes');
        }

Another words, is first_child definition the child of the root?(in this case , 'one' and then 'traffic' and then so on.. and therefore need to go down the chain in steps or can I say my parent is one and then first child is 'getthis' ?

 <one id="msn" type="shopping">
   <traffic>
       <daily value="on" />
       <weekly value="off" />
        <something>
            <somethingelse>
                  <getthis value="found" true="yes" />
            <somethingelse>
       </something>
       <monthly value="off" />
   </traffic>
  </one>
