EDI XML

This is a base/technical module for EDI (electronic data interchange) exchanges that use XML files. It does not add menus or screens for end users; it gives other EDI modules the tools to handle XML content.

What it provides: - A reusable XML handler component (edi.xml.handler) that other EDI components can use. - Reading XML: it converts an XML document into a Python dictionary so the data can be processed. - Writing XML: a helper converts a dictionary back into a valid XML string, with optional pretty formatting and encoding. - Validation: it checks XML content against an XSD schema file. The schema location must be given as module:path. If validation fails, it can either return the error message as text or raise the error, depending on the option chosen.

Business rules and behaviours: - The handler requires a schema path to be configured; if it is missing, an error is raised when the component is created. - If the schema file cannot be found, a clear error message is returned or raised.

It depends on the EDI component base module and requires the Python library xmltodict. It touches the EDI component framework rather than standard business models like sales or invoices.
