Beautiful Soup Dart

pub package tests codecov

Dart native package inspired by Beautiful Soup 4 Python library. Provides easy ways of navigating, searching, and modifying the HTML tree.


A simple usage example:

import 'package:beautiful_soup_dart/beautiful_soup.dart';

/// 1. parse a document String
BeautifulSoup bs = BeautifulSoup(html_doc_string);
// use BeautifulSoup.fragment(html_doc_string) if you parse a part of html

/// 2. navigate quickly to any element
bs.body!.a!; // navigate quickly with tags, use outerHtml or toString to get outer html
bs.find('p', class_: 'story'); // finds first element with html tag "p" and which has "class" attribute with value "story"
bs.findAll('a', attrs: {'class': true}); // finds all elements with html tag "a" and which have defined "class" attribute with whatever value
bs.find('', selector: '#link1'); // find with custom CSS selector (other parameters are ignored)
bs.find('*', id: 'link1'); // any element with id "link1"
bs.find('*', regex: r'^b'); // find any element which tag starts with "b", for example: body, b, ...
bs.find('p', string: r'^Article #\d*'); // find "p" element which text starts with "Article #[number]"
bs.find('a', attrs: {'href': ''}); // finds by "href" attribute

/// 3. perform any other actions for the navigated element
Bs4Element bs4 = bs.body!.p!; // navigate quickly with tags; // get tag name
bs4.string; // get text
bs4.toString(); // get String representation of this element, same as outerHtml
bs4.innerHtml; // get html elements inside the element
bs4.className; // get class attribute value
bs4['class']; // get class attribute value
bs4['class'] = 'board'; // change class attribute value to 'board'
bs4.children; // get all element's children elements
bs4.replaceWith(otherBs4Element); // replace with other element
... and many more
