Hello,
I'm new to mango. I'm importing a pointLocator with a regular expression:
"valueRegex":""id":"50009","type":"controlfunctionasset".?"ReferenceInput":"(.?)",".*?"cmddata""
{"assets":{"controlfunctionasset":[{"id":"50009","type":"controlfunctionasset","label":"VOLTAGE_REGULATION_CF","model":"voltageregulation","extant":"true","Ts":"0.017","Enabled":"false","Hold":"false","Reset":"false","ResetValue":"0.000","Output":"0.000","UpperLimitHit":"false","LowerLimitHit":"false","OperationFault":"false","ExternalFault":"false","ReferenceInput":"0.000","DebugLevel":"0","Initialized":"true","Gain":"1.000","PreGainOutput":"0.000","CompareInput":"0.000","CompareInputGain":"1.000","LimHi":"false","LimLo":"false","Vtest1":"0.000","Deadband":"0.010","MaxCommand":"1.000","MinCommand":"-1.000","Kv":"1.000","Kgv":"1.000","Kpv":"0.000","Kiv":"1.000","Krv":"1.000","Kdroopv":"0.000","Slew":"9.000","SlewDef":"1.000","QtestActive":"false","QtestCmd":"0.000","Unwind":"false","UsePControlOnly":"false","KpvActive":"0.000","KdroopvActive":"0.000","VRef":"0.000","Qvr":"0.000","PiErr":"0.000","POutput":"0.000","IOutput":"0.000","DroopSignal":"0.000","RampInput":"0.000","RampOutput":"0.000","cmddata":{"Enabled":"false","Hold":"false","Reset":"false","ResetValue":"0.000","ExternalFault":"false","ReferenceInput":"480.000","CompareInput":"0.000","MaxCommand":"2000.000","MinCommand":"-2000.000","Deadband":"4.800","Kv":"100.000"}}]}}
I would like the ReferenceInput after the cmddata? Not the first one. Dont know how the valueRegEx works? Is there a test site or tool I can use?
Much Appreciated,

"xid":"DP_50009_1", "loggingType":"ON_CHANGE", "intervalLoggingPeriodType":"MINUTES", "intervalLoggingType":"INSTANT", "purgeType":"YEARS", "pointLocator":{ "dataType":"NUMERIC", "ignoreIfMissing":false, "timeFormat":"", "timeRegex":"", "valueFormat":"", "valueRegex":"\"id\":\"50009\",\"type\":\"controlfunctionasset\".*?\"ReferenceInput\":\"(.*?)\",\".*?\"cmddata\""The above is the datapoint I'm importing.

I’m using mango to do this so. It will use a HTTP request to get the data which is returned in json.

If I'm understanding the problem correctly, the ordering of the JSON is guaranteed and you want the second ReferenceInput value, i.e.
"valueRegex":""id":"50009","type":"controlfunctionasset".?ReferenceInput.?"ReferenceInput":"(.?)",".?"cmddata""
regexpal.com has been useful to me.

When delete a datapoint, the meta datapoint used this datapoint will be affect, Can do some caution when delete one datapoint which be used in another meta point. :mrgreen: :oops:
