Lightweight HTML Pruning
Transforms raw HTML into a lean document or fragment by pruning optional tags and normalizing doctypes for embeddable output.
Capabilities
Normalize doctype
- Converts any provided HTML doctype to the short HTML5 form
<!doctype html>at the top of the output, preserving the remaining markup.<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN">becomes the short form while keeping content intact. @test
Strip optional wrappers
- Removes optional structural wrappers such as
<html>,<head>, and<body>when they only provide default containers and have no attributes, keeping head resources before body content in the resulting string. @test
Prune empty containers
- Eliminates empty non-void elements (including whitespace-only nodes) like
<div>or<section>when they have no children and no attributes, while preserving empty elements in a keep list (script,style,meta,link,img,br,hr). @test
Avoid auto-generated tags
- For HTML fragments without top-level
<html>or<body>tags, returns a trimmed fragment without inserting default wrappers, while still collapsing redundant whitespace and removing optional closing tags inside the fragment. @test
