How to select the meta tags and get the content value in Cheerio?

Question

I would like to select the meta tag with the og:title property and get the content text value from it i.e. Silver Surfer, I cannot figure how to approach this in Cheerio

<meta property="og:type" content="SILVER" />
<meta property="og:image" content="http://img.silversurfer.com/surfer.png"/>
<meta property="og:title" content="Silver Surfer" />
<meta property="og:url" content="https://www.silversurfer.com" />

This is my latest attempt so far var title = $('meta[property=og:title]').content

Answer 1

You need to use attribute css selector and to get the attribute use Cheerio::attr.

const cheerio = require('cheerio')
const $ = cheerio.load(`
<meta property="og:type" content="SILVER" />
<meta property="og:image" content="http://img.silversurfer.com/surfer.png"/>
<meta property="og:title" content="Silver Surfer" />
<meta property="og:url" content="https://www.silversurfer.com" />
`);

$('[property="og:type"]').attr('content');
