In your example below, you do have text in between ... you have text nodes comprised only of white-space characters.
If the white-space *is* significant, just check the value of the current node:
<xsl:if test=". = ''">
If the white-space *isn't* significant, trim leading and trailing just in case the input was "lazily" empty:
<xsl:if test="normalize-space(.)=''">
Note this is a common problem where users *think* an element is empty, but they've inserted a new-line to make the indentation look nice, not realizing they no longer have an empty element.
I hope this helps.
