Matt, 

It looks like Steve Lime's regular expression example will get you what you are 
looking for.  

One strategy to think about with MapServer (and any other Web map server) is 
that when you are looking for the best performance, you want to pre-process 
your data as much as possible.  This means pre-classifying your data if 
complicated expressions are necessary, projecting your data to get it all in 
the same spatial reference system, etc.  

MapServer can do on-the-fly projection, complicated expressions, etc. pretty 
efficiently.  But, if you can do these tasks once in pre-processing, they won't 
have to be done every time someone makes a map request.  

In your case, if performance matters, I would consider creating a new column in 
your data source and splitting out the two 'tags'.  An expression that is an 
exact string match will be faster than a more complicated expression.  

David.

Thanks, this looks great.
I will try it tonight, but I think is looking just right.
One more related question.  The column we are using is called 'Tag'
and the seemed to have grouped the 'class' and the 'title' in the one
column.  For example all secondary roads have the tag
"TVOP2"
but roads with the name 'smith st' will look like this
"TVOP2,SMITH ST"
So my  question is in the expression can I do a 'is like' query??  I am
guessing somthing like this
EXPRESSION 'TVOP2%'

Thanks for the great support

Matt  :)
