htmlparser2

A forgiving HTML/XML/RSS parser. The parser can handle streams and provides a callback interface.

Installation

npm install htmlparser2

A live demo of htmlparser2 is available here.

Usage

const htmlparser2 = require("htmlparser2");
const parser = new htmlparser2.Parser(
    {
        onopentag(name, attribs) {
            if (name === "script" && attribs.type === "text/javascript") {
                console.log("JS! Hooray!");
            }
        },
        ontext(text) {
            console.log("-->", text);
        },
        onclosetag(tagname) {
            if (tagname === "script") {
                console.log("That's it?!");
            }
        }
