InvoiceLint.Core

Native .NET rule engine for e-invoice XML. No Java at runtime. No Saxon. No remote calls.

Install

dotnet add package InvoiceLint.Core --version 0.1.0-dev.2

Quickstart

using System.Xml.Linq;
using InvoiceLint;

var result = Validator.Validate(xml, MyRulePack.Instance);
if (!result.IsValid)
{
    foreach (var issue in result.Issues)
        Console.WriteLine($"{issue.RuleId} {issue.Severity} {issue.Location}: {issue.Message}");
}

Host a pack (IRulePack) with an explicit rule list and catalog. InvoiceLint.Core does not use runtime reflection.

using System.Xml.Linq;
using InvoiceLint;

public sealed class MyRulePack : IRulePack
{
    public static MyRulePack Instance { get; } = new();

    public string Id => "toy";
    public RuleCatalog Catalog { get; } = new(
        "toy",
        "1.0",
        [new RuleCatalogEntry("toy-flag", "Shared", Severity.Fatal, "Flag must be ok.")]);
    public IReadOnlyList<IValidationRule> Rules { get; } = [new ToyFlagRule()];
    public bool Accepts(XElement root) => root.Name.LocalName == "Doc";
}

public sealed class ToyFlagRule : IValidationRule
{
    public string Id => "toy-flag";

    public IEnumerable<ValidationIssue> Evaluate(RuleContext context)
    {
        var flag = context.Root.Element(context.Root.Name.Namespace + "Flag");
        if (flag is null || flag.Value != "ok")
            yield return context.Fail(Id, flag);
    }
}

Load catalog JSON with RuleCatalogJson.Load(stream).

What this package is

MIT engine used by jurisdiction rule packs:

  1. InvoiceLint.Core — rule interface, catalog, validator, diagnostics.
  2. InvoiceLint.Testing — catalog checks and mutation helpers for pack tests.
  3. Commercial rule packs (later) — EN 16931, XRechnung, Peppol BIS, France CTC.

AeInvoice is the UAE PINT AE pack on this engine.
