react-native-html-parser

can use html parser in react-native, titanium, and anywhere. This is based on xmldom.

Install:

npm install react-native-html-parser

Example:

import React, {
    Component,
    View,
    Text,
    StyleSheet,
    TextInput,
    WebView,
} from 'react-native'


var DomParser = require('react-native-html-parser').DOMParser
class TestReactNativeHtmlParser extends Component {
    componentDidMount() {
        let html = `<html>
                        <body>
                            <div id="b">
                                <a href="example.org">
                                <div class="inA">
                                    <br>bbbb</br>
                                </div>
                            </div>
                            <div class="bb">
                                Test
                            </div>
                        </body>
                    </html>`
        let doc = new DomParser().parseFromString(html,'text/html')
        
        console.log(doc.querySelect('#b .inA'))
        console.log(doc.getElementsByTagName('a'))
        console.log(doc.querySelect('#b a[href="example.org"]'))
    }
    
}

or

var DOMParser = require('react-native-html-parser').DOMParser;
var doc = new DOMParser().parseFromString(
    '<html><body>'+
    '<div id="a" class="a">'+
        '<a class="b">abcd</a>'+
    '</div>'+
    '<div class="b">'+
        '<a href="aa" id="b">'+
    '</div>'+
    '</body></html>'
    ,'text/html');

console.log(doc.getElementsByAttribute('class', 'b'));
console.log(querySelecotr('.div.aa       class#a a'))
console.log(getElementsBySelector('div.aa#in[ii="a"]'))
console.log(doc.querySelect('div.a a.b'))
console.log('end')

or

import DOMParser from 'react-native-html-parser';

const html = `<p>Hello world <b>world</b> <i>foo</i> abc</p>`;    
const parser = new DOMParser.DOMParser();
const parsed = parser.parseFromString(html, 'text/html');
