Steve is right, I had only guessed that there might be a bug based on
the problem description, but we've been unable to reproduce the issue
that you report. I meant to reply on Friday asking for a testcase to
reproduce but I forgot.

While I'm glad it works (the regex should execute faster too) the other

have worked as well. Can you share the data you were using for some
testing?

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

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

Hi Mike,
I'm not sure about that, but try eq instead of =
EXPRESSION ('[TRAFFIC_TYPE]' eq 'Lane Closure' OR ...
Best Regards,

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
