DP filtering using dpNames (pattern negation condition)

[luis.bustamante]

Hello,

My question is related to DP filtering using dpNames().

I have a list of DP:
ASENSOR1
BMOTOR2
CVALVE3
CENT_SENSOR1
CENT_MOTOR2
CENT_VALVE3

I would like to know if in the dpNames() function a pattern negation condition can be introduced.

// It does not work.
dyn_string ds = dpNames("*:{!CENT_}*", "Device");

// It does work, but it is not dynamic.
dyn_string ds = dpNames("*:{A,B,CV}*", "Device");

Thanks.

Best regards,
Luis Miguel BP.

Complex patterns are only possible with the 'regexp' functions, which unfortunately do not work on dyn_strings.

You could get all dps from the type and check with a for loop and 'regexpIndex("^(?!CENT_).+$", ...)' which dps match your filter.

Thank you very much for your response.

I will get all the records and remove the ones I don't need.

This is the simplest way I have found:
dyn_string ds = dpNames("*", "Device");
for (int i = ds.count(); i > 0 ; i--) if (ds.contains(":CENT_") || ds.contains(":_mp_")) dynRemove(ds, i); ds.sort();

Best regards,
