Does anyone know if/what restrictions we have on regular expressions
within mapserver. I have a perl regular expression that matches 44 of
120 counties in Kentucky:
EXPRESSION
/(?-xism:(?i:(?=[abcfghjlmnorstw])(?:b(?:o(?:y(?:d|le)|urbon)|u(?:llitt|tler)|(?:arr|rack)en)|c(?:a(?:rter|sey)|(?:hristia|rittende)n|lark)|f(?:ayette|leming|ulton)|h(?:a(?:ncock|rt)|enderson)|l(?:e(?:tcher|wis)|(?:incol|oga|yo)n)|m(?:a(?:di)?son|e(?:rcer|tcalfe)|o(?:ntgomery|rgan)|ccracken|uhlenberg)|s(?:helby|impson|pencer)|t(?:aylor|odd)|w(?:ayne|oodford)|adair|grant|johnson|nicholas|oldham|russell)))/
This has been optimized and uses some embedded modifiers. This works
fine in Perl but does not match anything in mapserver.
Any thoughts on how to modify this to work with mapserver. While this
looks very convoluted, it is generated from a list of words and is high
efficient when matching.
Thoughts?

PS: Using 5.6.x at the moment.
