What is posthtml-parser?

The posthtml-parser npm package is a tool used to parse HTML into an Abstract Syntax Tree (AST). This allows developers to manipulate HTML content programmatically, making it easier to perform tasks such as transforming HTML structures, extracting specific elements, and integrating with other tools in the PostHTML ecosystem.

What are posthtml-parser's main functionalities?

Parsing HTML to AST

This feature allows you to parse a string of HTML into an Abstract Syntax Tree (AST). The AST can then be manipulated programmatically.

const parse = require('posthtml-parser');
const html = '<div class="example">Hello World</div>';
const ast = parse(html);
console.log(ast);

Handling HTML fragments

This feature allows you to parse HTML fragments and control parsing options such as whether to convert tag names to lowercase.

const parse = require('posthtml-parser');
const fragment = '<span>Fragment</span>';
const ast = parse(fragment, { lowerCaseTags: false });
console.log(ast);

Integration with PostHTML plugins

This feature demonstrates how to integrate the parser with PostHTML plugins to transform HTML content. In this example, a plugin is used to change all <div> tags to <section> tags.

const posthtml = require('posthtml');
const parse = require('posthtml-parser');
const html = '<div class="example">Hello World</div>';
posthtml()
  .use(tree => {
    tree.match({ tag: 'div' }, node => {
      node.tag = 'section';
      return node;
    });
  })
  .process(html)
  .then(result => console.log(result.html));
