[flexcoders] How to access last node atributes with e4x?

[mocalocamm]

This is my xml:

<list>
 <month month="3" year="2007">
  <day date="01" impressions="407"/>
  etc...
 </month>
 <month month="4" year="2007">
  etc...
  <day date="30" impressions="657"/>
 </month>
</list>

More months will be added with time so I need to set a variable always
with the values of the lastest month:

endDate = new Date(2007,5,30)

Accessing the beginning of the month is easy enough:
startDate = new
Date([EMAIL PROTECTED],[EMAIL PROTECTED],[EMAIL PROTECTED]);

But how to get to the last node attributes if the last mode is
constantly changing?

Thanks for any help,
Moca
