element <pub> can occur anywhere after <info> in the xml. Here is the example with the attribute level to pub. 
--------------------------------------------------
<test2>
<info>
 <requirement>
 <level1>
 <para></para>
<pub level="1"></pub>
 </level1>
 </requirement>
 </info>
 </test2>

Please see the new example above.
