[mapserver-users] multiple matches in $classObj->setexpression

[Puneet Kishor]

Thanks Steve for responding.

As you know, I figured out the regexp solution like you also suggested...

> $oClass->setexpression("/^foo$|^bar$|^baz$/");

actually, since I wanted a full string match of many strings, I did the 
following...

$oClass->setexpression("/(foo)|(bar)|(baz)/");

it works peachy.

For now my problem is solved. However, I still can't get logical 
expressions to works, not at all. I can imagine wanting to do inequality 
operations such as...

$oClass->setexpression("(([CI] < 5) or ([CI] > 7) or ([CI] eq 
\"Puneet\"))");

but, no success. I have tried a variety of different syntactic 
constructs (including different case combinations as well, even though I 
know that the attributes are all upper-case), starting with the simplest 
possible ([CI] = 5) and failed.

I _am_ using PHP/Mapscript right now, but also re-writing the entire 
application in Perl/Maspscript.

Why are my logical expressions failing? Is there something very obvious 
that I am overlooking?
