[mapserver-users] class expression question

[Lime, Steve D (MNIT)]

You can use regexes:

CLASSITEM 'road_type'
CLASS
  EXPRESSION /^I-/
  ...
END

or

CLASS
  EXPRESSION ('[road_type]' ~ '^I-')
   ...
END

Subject: [mapserver-users] class expression question

I'd like to classify road data according to road type.  This includes Interstate highways, where the road name attribute starts with "I-", such as "I-95", "I-295", etc.  So I'd like to create a class where '[roadname]' like 'I-%'


-          What is the correct syntax to do this?
