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.

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 :) -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Real-life-sample-of-a-Mapfile-for-shp-files-on-WMS-tp5718787p5719102.html Sent from the Mapserver - User mailing list archive at Nabble.com. _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
