Deterministic, configurable HTML normalization for hashing and change detection

Installation

dotnet add package Soenneker.Html.Normalizer

Usage

using Soenneker.Html.Normalizer.Models;

HtmlNormalizationResult result = await normalizer.NormalizeAndHash(renderedHtml);

Console.WriteLine(result.Html);
Console.WriteLine(result.Hash);

The default profile removes common runtime artifacts while preserving indexable content:

  • HTML comments
  • <style> elements
  • scripts other than application/ld+json
  • nonce attributes
  • Blazor _bl_* element-reference attributes
  • element IDs and common HTML/ARIA attributes that reference them
  • formatting-only inter-element whitespace

It also normalizes line endings and sorts ordinary HTML attributes. Hashing uses XXH3 through Soenneker.Hashing.XxHash, producing a lowercase 64-bit hexadecimal hash for fast, non-adversarial change detection.

Application-specific normalization

using System.Text.RegularExpressions;
using Soenneker.Html.Normalizer.Options;

var options = new HtmlNormalizationOptions();

options.RemoveSelectors.Add("[data-runtime-only]");
options.RemoveAttributes.Add("data-request-id");
options.Replacements.Add(new HtmlNormalizationReplacement(
    "session-[a-f0-9]{32}",
    "session-id",
    RegexOptions.IgnoreCase | RegexOptions.CultureInvariant));

string normalized = await normalizer.Normalize(renderedHtml, options);

Dependency injection

using Soenneker.Html.Normalizer.Registrars;

services.AddHtmlNormalizerAsSingleton();
// or services.AddHtmlNormalizerAsScoped();

Browser readiness is intentionally outside this package. Wait for hydration or another application-specific readiness signal before capturing and normalizing rendered HTML.
