[removed] How to correct indentation in HTML string? [closed]

Answer 1

The js-beautify tool can work with html, and has an api. It's probably the easiest way to do what you want.

After installing it with node:

var beautify_html = require('js-beautify').html;

result = beautify_html(htmlstring);

To use it in a browser, you need to include all the beautify*.js scripts in this directory and use window.html_beautify.
