Given that it is known, in this test, that the context node is a 'B', this 
could be

 <xsl:for-each select="B">
  <xsl:if test="not(following-sibling::B)">
   <xsl:value-of select="." />
  </xsl:if>
 </xsl:for-each>

... but I don't think it answers the OP's requirement.

As I recall, Mike suggested child::A/preceding-sibling::B[1], which isn't 
considered adequate because the context node is already a B, not the parent 
of the As and Bs. So the requirement is not to *select* all B nodes that 
have no Bs after them before As, but to test true on a B context node that 
is (as the OP said) "the last 'B' node that occurs before the next 'A' node".

In other words, the context node is a B, and the test should detect that 
the directly following sibling is not a B, but that there is an A following 
sibling.

This is

test="following-sibling::*[1][not(self::B)] and following-sibling::A"

Cheers,
Wendell
