You can do it using the count() function:

  count(*) = 1

returns true if the context node has exactly one child element.

Another method is to test whether there is a second child element:

  not(*[2])

returns true if there isn't a second child element (i.e. if there are
0 or 1 child elements).

Cheers,

Jeni
