How to validate an XML File in Python

File validation is the first line of protection against all the potential problems that can easily arise from invalid files, whether corrupted, mislabeled, or what have you. XML validation can be a particularly difficult nut to crack without the right tool. I have just such a tool for you today: an API designed for this exact problem. Let me help you get it set up.

Begin by using pip install to bring in our client files:

pip install cloudmersive-convert-api-client

Now it’s a matter of giving the validate_document_xml_validation function what it needs: an API key, API instance, and an XML file.

from __future__ import print_functionimport timeimport cloudmersive_convert_api_clientfrom cloudmersive_convert_api_client.rest import ApiExceptionfrom pprint import pprint# Configure API key authorization: Apikeyconfiguration = cloudmersive_convert_api_client.Configuration()configuration.api_key['Apikey'] = 'YOUR_API_KEY'# Uncomment below to setup prefix (e.g. Bearer) for API key, if needed# configuration.api_key_prefix['Apikey'] = 'Bearer'# create an instance of the API classapi_instance = cloudmersive_convert_api_client.ValidateDocumentApi(cloudmersive_convert_api_client.ApiClient(configuration))input_file = '/path/to/file' # file | Input file to perform the operation on.try:# Validate an XML fileapi_response = api_instance.validate_document_xml_validation(input_file)pprint(api_response)except ApiException as e:print("Exception when calling ValidateDocumentApi->validate_document_xml_validation: %s\n" % e)

Give it a quick test run and you will see that XML validation is now at your command. If you like how much time this just saved for you, then I recommend a quick perusal of the documentation for the rest of this API, as its library contains hundreds of other great functions that can save you loads of time.

There’s an API for that. Cloudmersive is a leader in Highly Scalable Cloud APIs.
