Re: [mapserver-users] v5.0.0 - CLASSITEM has double quote in field value
Hi Mike,
I'm not sure about that, but try eq instead of =
EXPRESSION ('[TRAFFIC_TYPE]' eq 'Lane Closure' OR ...
Best Regards,
Alexandre

Hi All
I've got a MapFile that used to work fine in v4.10 but now fails in v5.0
Basically the CLASSITEM field has double quote in field value and this
is then returning an error - msEvalExpression: Expression parser
error. Failed to parse expression
The CLASS EXPRESSION looks like this
CLASSITEM 'TRAFFIC_TYPE'
CLASS
EXPRESSION ('[TRAFFIC_TYPE]' = 'Lane Closure' OR
'[TRAFFIC_TYPE]' = 'Multi-Way Signals' OR '[TRAFFIC_TYPE]' = 'Road
Closure' OR '[TRAFFIC_TYPE]' = 'Stop/Go Boards' OR '[TRAFFIC_TYPE]' =
'Two-Way Signals')
STYLE # Severe (RED)
SYMBOL 'triangle'
SIZE 9
COLOR 255 0 0
OUTLINECOLOR 0 0 0
END
END
I've tried double quote vs. single quotes in the map file but to no avail
Anyone any thoughts?
Kind regards
Mike

Re: [mapserver-users] v5.0.0 - CLASSITEM has double quote in field value
I've been told by developers that there seems to be a bug when using
in the expression parser...
You should use a regular expression instead like the following :
EXPRESSION /^Lane Closure$|^Multi-Way Signals$|^Road Closure$|^Stop\/Go
Boards$|^Two-Way Signals$/
See at : http://mapserver.gis.umn.edu/docs/howto/msexpressions

thanks Alexandre but unfortunately it didn't work
Do you know if there is a way of forcing MapServer to read out the
literal string i.e. sort of like escaping it? in .NET you can say
@stringvariable and it will ignore quotes inside etc?
Cheers

Alexandre
Excellent - that works!
FYI - This is why I believe that Open Source can easily prevail even when
people put down the 'many eyes see more bugs' notion. In another life I
worked with / as a partner for a proprietary company (now you can buy
franking machines from the same parent company wink wink nudge nudge) and
you'd never get this response so quickly and also having 'had it from the
horses mouth a.k.a. Developers' that there is an issue and this is the best
way around it.
Thanks so much Alexandre
Kind regards
Mike
