in reply to Perl panicking XML::LibXML::Reader copyCurrentNode

It works for me. You haven't provided any input data, so I constructed my own: 
<root>
<child/>
</root>

But even when trying to use an XML that matches the pattern, it still works without crashing: 

<?xml version="1.0" encoding="utf-8"?>
<martif>
  <text>
    <body>
      <termEntry>1 2 3 4 5 6 7 8 9</termEntry>
      <termEntry>abcdefghijklmnopqrstuvwxyz</termEntry>
      <termEntry/>
      <termEntry/>
      <termEntry/>
      <termEntry/>
      <termEntry/>
      <termEntry/>
      <termEntry>
        <unknown1>
        </unknown1>
        <unknown1>
        </unknown1>
      </termEntry>
    </body>
  </text>
</martif>
