How it works

from primestg.report import Report

# xml is a basestring with a filename or a file object with the report
report = Report(xml)

# get all values of the report
values = report.values

# get the values of first concentrator
values = report.concentrators[1].values

# get the values of second meter of the first concentrator
values = report.concentrators[1].meters[2].values

# get the first value set of second meter of the first concentrator
values = report.concentrators[1].meters[2].measures[1].values

# get the parameters of the first concentrator from report S12
values = report.concentrators[1].parameters[1].values

Warnings property

All reports supported by the library have a warnings property that informs of problems found while parsing the contents of it. Depending on the type of report the warnings will be structured one way or another.

Meter information report:

The best way to get the warnings for these reports would be asking for the warnings of every meter in it.

for meter in cnc.meters:
    if meter.warnings:
        warnings.append(meter.warnings)

These will give us a list of dictionaries where each of them will have the serial name of the meter as a key and a list of strings with every exception found while reading as a value.

Concentrator information report:

To obtain the warnings from a concentrator report we will use the warnings property from the concentrator object directly.

for cnc in self.report[key].concentrators:
    if cnc.warnings:
        warnings.append(cnc.warnings)

This give us a list of strings where each one is the message of an exception found while reading.
