xsl:macro example?

Hello,
  Could someone point me to an example of how to use xsl:macro, including both
the xml and xsl that make use of macro:invoke?  I'm having a hard time finding
an example of how this works.
  BTW, what is the best XML/XSL book out there?  I've been a programmer for the
past 6 years or so and can pick up things rather quickly, but I have no XML/XSL
experience.
  Thanks,
   -M@
