How ?

Implementation steps:

  1. Downloads the content of a web page
  2. Meta-scrape page details (title, author, date, etc)
  3. Sanitizes the ugly HTML
  4. Minifies the disinfected HTML
  5. Converts the result into clean Markdown text

This project depends on the A-Extractor project, a database of expressions used for extracting content from blogs and articles.


The goals of the project are are:

  1. Good text extraction
  2. More useless text is preferred, instead of cutting from the actual article by mistake
  3. Extracting media (images, videos, audio) is not that important
  4. Extraction speed is not that important


Clean-mark was tested on all major news sites. On some websites, the text, or links are cut from the article. In this case, you have to manually edit the resulted text,


please raise an issue on A-Extractor with the link that doesn't work and we'll add it in the database, so that next time, the text will be extracted correctly.
