If you used the XML Parser functions, this would be no problem at all.
See http://www.php.net/manual/ref.xml.php
In your element handler, set a flag when you receive a "lowestusedprice"
element, and then the next "amount" will be the one you want (clear the
flag when you receive a closing "lowestusedprice".
