IRIS-validator

iris-validator is a small python module for validation stationxml files against the IRIS StationXML Validation Rules found at:

https://github.com/iris-edu/stationxml-validator/wiki/StationXML-Validation-Rule-List

It has a limited API and a command-line script

Installation

Requirements

obspy >= 1.2

These requirements should be automatically installed for you (see below).

Install

Easy install from pypi:

>pip install iris-validator

Alternatively, you can Clone the repository and install:

>git clone https@gitlab.isti.com:mhagerty/iris-validator.git 
>cd iris-validator
>pip install .

Usage:

Once you have installed it, you should be able to run it as a python module from any directory.

iris-validator can either test your own xml against the iris validation rules (--infile /path/to/your.xml) or it can run through a suite of tests that test known xml snippets against each rule (--run-tests). The tests are mainly there to confirm that the iris rules are being applied correctly (e.g., to test the code itself).

>iris-validator

usage: iris-validator [-h] (--infile INFILE | --run-tests)

required arguments: // One of these is required
  --infile INFILE       // path-to StationXML file, e.g., --infile=/path/to/foo.xml
  --run-tests           // Run IRIS Validator Test Files

> iris-validator --run-tests
Check file:F1_101.xml against Rule:101
SUCCESS: xmlfile=[F1_101.xml] FAILED as expected
Check file:F1_110.xml against Rule:110
SUCCESS: xmlfile=[F1_110.xml] FAILED as expected
Check file:F2_110.xml against Rule:110 
SUCCESS: xmlfile=[F2_110.xml] FAILED as expected
...
Check file:P1_112.xml against Rule:112
SUCCESS: xmlfile=[P1_112.xml] PASSED as expected
...
Check file:F1_422.xml against Rule:422 
SUCCESS: xmlfile=[F1_422.xml] FAILED as expected
Check file:F1_423.xml against Rule:423
SUCCESS: xmlfile=[F1_423.xml] FAILED as expected

Additional cmd line options:

usage: iris-validator [-h] (--infile INFILE | --run-tests)
       [-s STATION] [-c CHANNEL] [-n NETWORK] [-l LOCATION] [-def] [-i IGNORE [IGNORE ...]]

options:
  -h, --help            show this help message and exit
  -s STATION, --station STATION, --sta STATION
                        Specify a station code, wildcards are allowed
  -c CHANNEL, --channel CHANNEL, --cha CHANNEL
                        Specify a channel code, wildcards are allowed
  -n NETWORK, --network NETWORK, --net NETWORK
                        Specify a network code, wildcards are allowed
  -l LOCATION, --location LOCATION, --loc LOCATION
                        Specify a location code, wildcards are allowed
  -def, --seismic-only, --seismic_only
                        Only scan default_seismic_channels in: {[BEHSG][HNL][123ENZ]}
  -i IGNORE [IGNORE ...], --ignore IGNORE [IGNORE ...]
                        Specify list of rule codes to ignore

For example, to ignore specific rule checks you can do:

  >iris-validator --infile /path/to/file.xml -i 321,420 421 422 ...

-n, -s, -c, -l flags can be used to select only these channels for scanning

API

To use the module from within your own python script, follow the example below:

from iris_validator import stationxml_validator

validator = stationxml_validator('path/to/some/stationxml.xml')

validator.validate_inventory()

print("[ERRORS]:\n")
for msgs in validator.errors:
    for i, msg in enumerate(msgs):
        if i == 0:
            print(msg)
        else:
            print("%7s %s" % (' ', msg))

print("\n[WARNINGS]:\n")
for msgs in validator.warnings:
    for i, msg in enumerate(msgs):
        if i == 0:
            print(msg)
        else:
            print("%7s %s" % (' ', msg))

Note some other things you can do include:

validator.validate_rule('420')          // You can test your stationxml file against one rule at a time
