Hi Johan: Are you looking for just two classes, one for records that start with "LADE" and another for everything else? If so you can just omit the expression from the second class and it will function as a default class so everything that doesn't match the first will be assigned the second. It's faster to execute than trying to expressly define a second regex. Doesn't solve the regex error but then again you may not need to.

All: Regex neophyte, using MS 5.4.2 in FGS on Ubuntu Server 9.10, I wish to render two classes based on content in a PostGIS field. For the first CLASS I want all records that start with "LADE", and using NAME "LADE" EXPRESSION /^LADE.*/ appears to return the expected records. However, for the second CLASS I want all records that DO NOT start with "LADE", but using NAME "Other" EXPRESSION /^(?!LADE).*/ does not return any records and the log contains msEvalExpression() error: Regular expression error. Invalid regular expression. Examples out in the ether all indicate that this "negative lookahead" is supposed to do exactly what I want. What am I doing wrong in this instance? Thanks! /Johan. ---------------------- Johan Forsman Geologist Safe Drinking Water Program Louisiana Department of Health and Hospitals Office of Public Health Telephone: 225.342.7309 Telefax: 225.342.7303 _______________________________________________ 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
