how I put condition for two attribute in Xpath?

how I can get PointLocation by Xpath PointBrush which content exactly x and y. Not: I write Xpath inside My java.

My Xpath:

  NodeList brushNode="PointBrush/PointLocation[x['" + entity.getPointLocation().getX() + "'] | /y['" + entity.getPointLocation().getY() + "']]"

my XMl:

       <PointBrush>
         <PointLocation>
            <x>36.473796987533674</x>
            <y>35.49325534870742</y>
         </PointLocation>
      </PointBrush>
      <PointBrush>

   <PointBrush>
         <PointLocation>
            <x>36.4723496987533674</x>
            <y>35.1234534870742</y>
         </PointLocation>
      </PointBrush>
      <PointBrush>
