Application for exporting data from specific XML file

XML Data Exporter

This is a Flask application for parsing data about available products from XML file.

First, the application downloads the latest data in ZIP archive file, which is then extracted and the data are parsed from the extracted XML file. If the ZIP file is already available, the application will use the data from it. Latest ZIP file can be manually updated using an endpoint.

User can choose from four options, what he desires to return:

1 - Count of all products
2 - List of all products
3 - List of product with spare parts
4 - Download latest data

Products structure

Product names are stored in the items node in the root of the XML file. Some products have also available spare parts in parts node where categoryId attribute have value of 1 (spare parts category).

REST API endpoints

The application offers basic REST API for accessing the data. Index page has a signpost to all available endpoints.

The endpoints are listed below (all endpoints are using the HTTP GET method):

/ - Index page with a signpost to all endpoints
/products/1 - Returns count of all products
/products/2 - Returns list of all products
/products/3 - Returns list of products with spare parts
/products/4 - Downloads latest data

Downloading the latest data is made using GET endpoint, for ease of testing. Correct HTTP method should be PUT.

Docker

The application can be started using Docker command docker-compose up.

Tests

The application has unit tests for all three data endpoints. Tests can be run using pytest command pytest test_app.py.
