Turns a UBL-TR e-Invoice or e-Archive XML document into clean JSON: parties, line items, taxes and totals.

Works regardless of the namespace prefix the sender used (cbc:, cac:, ns0:), normalises single-line documents into arrays, and reports amount mismatches in warnings instead of returning quietly wrong totals. The job that costs accounting and expense software the most engineering time.

In the GET form every field is a query parameter; object and array fields are JSON-encoded.
