I usually use XML::XSH2 for XML manipulation. To search for nodes, it uses XPath. In this case, you can use:
ls //*[0=count(./* | ./@* | ./text() | ./comment() | ./processing-inst
+ruction())]

(You did not specify what to do with comments and processing instructions. You might need to change the XPath accordingly.)
