[mapserver-users] How can i get an attribute value of a specific shape in the mapfile?

[jjwang]

Is there any way to get an attribute value of a specific shape in the
mapfile?
For example:
I want to know the value of the attribute 'AREA' of a shape whose 'NAME' is
'REDFERN'.
So that I can use it in the EXPRESSION like this:
CLASS
 EXPRESSION ([AREA] > [the area value of shape whose name is 'redfern'])
 ...
END

JJ
