Off the top of my head, you can replace bQ{}b and b[1]b with the
empty
string, tokenize on b/b, get the last three members, and string-join
them back together with b/b.

Youbll have to exercise a little more care if the elements might be in a
namespace or if you might get some other index (b[2]b for example).

This works, but I canbt immediately think of a way to avoid the $parts
variable. But someone cleverer than me will probably post a purely
functional answer thatbs eluding me.

  <xsl:variable name="path"
                select="'/Q{}AeroPublication[1]/Q{}airports[1]/Q{}airport[1]/
Q{}icaoCode[1]'"/>

  <xsl:variable name="parts"
                select="replace($path, 'Q\{\}', '')
                        => replace('\[\d+\]', '')
                        => tokenize('/')"/>
  <xsl:sequence select="string-join($parts[count($parts) - position() lt 3],
'/')"/>

                                        Be seeing you,
                                          norm
