advanced-html-parser
Can use html parser in react-native, titanium, and anywhere. This is based on xmldom.
This library is based on react-native-html-parser where it has much more features and it can decode almost all charecters set, also
added support to CSS3 selectors and typescript.
Install:
npm install advanced-html-parser
Example
const IDOMParser = require("advanced-html-parser");
const doc = IDOMParser.parse(`<div class="test" href="google"><span> test </span><span> test </span></div>`);
const attr = doc.documentElement.querySelector("span").closest(".test").getAttribute("href");
CSS3 Selector support
The library uses css-select
and it support all advanced selectors css-select
support like
#info > .description > .small strong:first-child span
and more.
See css-select for more info.
Speed up the parsing
The libray is very fast, and if you want to use it to scrap some data from website. then using the settings below may speed the parsing.
const doc = IDOMParser.parse(page, {
ignoreTags: ["script", "style", "head"]
});
