xpath query

hi all,
what could be the xpath query with the foll. xml, to select all the
nodes with apply="1" in the LEVEL2 from ROOT.

<ROOT>
<LEVEL1>
<A>
   <a apply="1">100</a>
   <b apply="1">100</b>
   <c>100</c>
</A>
</LEVEL1>

<LEVEL2>
<B>
   <a>100</a>
   <b apply="1">100</b>
   <c>100</c>
</B>
<C>
   <a>100</a>
   <b>100</b>
   <c apply="1">100</c>
</C>
<LEVEL2>
</ROOT>

I tried using /ROOT/LEVEL2/*[@apply='1']. But it doesn't select the
intended nodes.

Thanks
