Validating a yaml document in python

Question

One of the benefits of XML is being able to validate a document against an XSD. YAML doesn\'t have this feature, so how can I validate that the YAML document I open is in th

Answer 1

I wrapped some existing json-related python libraries aiming for being able to use them with yaml as well.

The resulting python library mainly wraps ...

• jsonschema - a validator for json files against json-schema files, being wrapped to support validating yaml files against json-schema files in yaml-format as well.

• jsonpath-ng - an implementation of JSONPath for python, being wrapped to support JSONPath selection directly on yaml files.

... and is available on github:

https://github.com/yaccob/ytools

It can be installed using pip:

pip install ytools

Validation example (from https://github.com/yaccob/ytools#validation):

import ytools
ytools.validate("test/sampleschema.yaml", ["test/sampledata.yaml"])

What you don't get out of the box yet, is validating against external schemas that are in yaml format as well.

ytools is not providing anything that hasn't existed before - it just makes the application of some existing solutions more flexible and more convenient.
