README

Hypertext

A PHP HTML to pure text transformer that beautifully handles various and malformed HTML.

Hypertext is excellent at pulling text content out of any HTML based document and automatically:

  • Removes CSS
  • Removes scripts
  • Removes headers
  • Removes non-HTML based content
  • Preserves spacing
  • Preserves links (optional)
  • Preserves new lines (optional)

It is directed at using the output in LLM related tasks, such as prompts and embeddings.

Installation

composer require stevebauman/hypertext

Usage

use Stevebauman\Hypertext\Transformer;

$transformer = new Transformer();

// (Optional) Filter out specific elements by their XPath.
$transformer->filter("//*[@id='some-element']");

// (Optional) Retain new line characters.
$transformer->keepNewLines();

// (Optional) Retain anchor tags and their href attribute.
$transformer->keepLinks();

$text = $transformer->toText($html);
