How can I validate JSON and XML data?

You can validate JSON using tools like JSONLint, and for XML, you can use XML validators like XML Validator.

Common JSON errors include missing commas, unquoted keys, and trailing commas. For XML, unclosed tags and incorrect nesting are frequent issues.

Are there libraries for validating these formats in Python?

Yes, you can use jsonschema for JSON validation and lxml or xmlschema for XML validation in Python.

Can you show me an example of validating JSON in Python?

Sure! Here's a simple example:

import json
from jsonschema import validate, ValidationError

# JSON data
data = {'name': 'John', 'age': 30}

# Schema
schema = {'type': 'object', 'properties': {'name': {'type': 'string'}, 'age': {'type': 'integer'}}}

# Validate
try:
    validate(instance=data, schema=schema)
    print('JSON is valid!')
except ValidationError as e:
    print('JSON is invalid:', e.message)
