Hi Lansing,

I have put ^ at the beginning of the regex but the same error is
reproduced. I have tested it with the time expression and without it.

<collection
> spec="/data/current/opendap/observational/mooring/weather_station/station_salines-ime_met002/L1/**/^.*_station-salines_ime-met002_L1_#yyyy-MM#.nc$"
> />
> <collection
> spec="/data/current/opendap/observational/mooring/weather_station/station_salines-ime_met002/L1/**/^.*_station-salines_ime-met002_L1_\d{4}-\d{2}.nc$"
> />


Cheers,
Kristian
