I'm a fan of Python library BeautifulSoup. It's feature-rich and very easy to use. But when I am working on a small react-native project, and I tried to find a HTML parser library
like BeautifulSoup, I failed.
So I want to write a HTML parser library which can be so easy to use just like BeautifulSoup in Javascript.
JSSoup uses tautologistics/node-htmlparser as HTML dom parser,
and creates a series of BeautifulSoup like API on top of it.
JSSoup supports both node and react-native.
JSSoup tries to use the same interfaces as BeautifulSoup so BeautifulSoup user can use JSSoup seamlessly.
However, JSSoup uses Javascript's camelCase naming style instead of Python's underscore naming style.
Such as find_all() in BeautifulSoup is replaced as findAll().
$ npm install jssoup
//react-native
import JSSoup from 'jssoup';
// nodejs
var JSSoup = require('jssoup').default;
var soup = new JSSoup('<html><head>hello</head></html>');
var soup = new JSSoup('<html><head>hello</head></html>');
var tag = soup.find('head');
tag.name
// 'head'
tag.name = 'span'
console.log(tag)
//<span>hello</span>
var soup = new JSSoup('<tag id="hi" class="banner">hello</tag>');
var tag = soup.nextElement;
tag.attrs
// {id: 'hi', class: 'banner'}
tag.attrs.id = 'test';
console.log(tag)
// <tag id="test" class="banner">hello</tag>
var data = `
<div>
<a>1</a>
<b>2</b>
<c>3</c>
</div>
`
var soup = new JSSoup(data);
var div = soup.nextElement;
var b = div.nextElement.nextElement;
// b.string: '2'
var a = b.previousElement;
// a.string: '1'
var soup = new JSSoup(data);
var div = soup.nextElement;
var a = div.nextElement;
var b = a.nextSibling;
var c = b.nextSibling;
c.nextSibling == undefined;
div.contents
// [<a>1</a>, <b>2</b>, <c>3</c>]
div.descendants
// [<a>1</a>, 1, <b>2</b>, 2, <c>3</c>, 3]
div.parent == soup
b.extract();
div.contents
// [<a>1</a>, <c>3</c>]
b.extract();
div.append(b)
div.contents
// [<a>1</a>, <c>3</c>, <b>2</b>]
var data = `
<div>
<div class="h1"></div>
<a>hello</a>
</div>
`
var soup = new JSSoup(data);
soup.findAll('a')
// [<a>hello</a>]
soup.findAll('div', 'h1')
// [<div class="h1"></div>]
var data = `
<div>
<p> hello </p>
<p> world </p>
</div>
`
var soup = new JSSoup(data);
soup.find('p')
// <p> hello </p>
var soup = new JSSoup('<html><head>hello</head></html>');
soup.nextElement.prettify()
// <html>
// <head>
// hello
// </head>
// </html>
div.text
// '123'
div.getText('|')
// '1|2|3'
b.string == '2';
var soup = new JSSoup('<html><head>hello</head></html>');
soup.string == 'hello';
npm test
There's a lot of work need to be done.
