If you've already used normalize-space() then you just need to test for
empty string, ie
<xsl:if test="normalize-space(.)='')> </xsl:if>
If you want to check it wasn't originally empty
<xsl:if test="not(.='') and normalize-space(.)='')> </xsl:if>

By default MS's DOM builder discards white space nodes, so your
stylesheet never gets to see them.
