Bob,
I do it this way (you'll need to figure out your specific REGEX though, I have
a column (F_CLASS) for classifying the HIGHWAY labels in the data)

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?
