cheerio

官方文档指路：https://github.com/cheeriojs/cheerio/wiki/Chinese-README

Fast, flexible, and lean implementation of core jQuery designed specifically for the server.

极其灵活：cheerio使用了@FB55编写的非常兼容的htmlparser2，因此它可以解析几乎所有的HTML和XML

const cheerio = require(‘cheerio’);
const $ = cheerio.load(‘

…‘);

const $ = cheerio.load(‘

…‘, {
normalizeWhitespace: true,
xmlMode: true
});

These parsing options are taken directly from htmlparser2, therefore any options that can be used in htmlparser2 are valid in cheerio as well. The default options are:
{
withDomLvl1: true,
normalizeWhitespace: false,
xmlMode: false,
decodeEntities: true
}

Forgiving html and xml parser
