First note that your example is not a well-formed xml document.

The one-line solution is:

<xsl:template match="/*/*[not(*[not('' = normalize-space())])]"/>

The above empty rule will match all children of the top element )in your case
"FirstSection", "SecondSection", ...)  that do not have any element child whose
string value is not whitespace-only. And because the rule is empty, all matching
nodes will simply be ignored. 

Hope this helped.
