XSLT - how to match any non-text node children?

Question

I'm new to XSLT and I can't figure out how to get an xsl:if that matches when there are no child tags.

I want this to match:

<context>
    howdy
</context>

And this not:

<context>
    <child>
        howdy
    </child>
</context>

Answer 1

the relevant xpath expression should look like:

//context[not(./*)]

Answer 2

You could also specify count(child::*) = 0 .
