Firstly, your Content1 elements are not empty, they contain whitespace text
nodes. If you want to treat them as empty, the simplest way is to strip the
whitespace by writing

<xsl:strip-space elements="*"/>

After that, you can simply test <xsl:if test="SectionSection=''"> which will
be true only if the element contains no (unstripped) text nodes, at any
depth.
