But of course after seeing Mike Kay's nice test in another thread, I realized a slightly more elegant and efficient version would be

<xsl:if test="child::node()[normalize-space(.)][1][self::para]">

...which reveals further complications (funny how these things are). We have to make sure it's skipped only if it's a whitespace-only _text_ node (not, say, an empty element node). So....

<xsl:if test="child::node()[not(self::text()) or normalize-space(.)][1][self::para]">

The first predicate evaluates to true if the child node is not a text node or if it has a non-whitespace string value. The second chooses the first of these. The third checks to see whether it's a para element.

For evident reasons, that <xsl:strip-space .../> at the top level will be preferable, if you can use it.
