How can I scrape hidden elements from HTML?

How can I perform the hidden data scraping in HTML. The data is there on the HTML head, but those are hidden meta tags with and the value I want to extract can be found on content property.

  <meta xmlns:og="" property="og:upc" content="2633" />
  <meta xmlns:og="" property="product:price:amount" content="419.99" />
  <meta xmlns:og="" property="product:price:currency" content="USD" />

I am able to get the meta tag with ‘meta’ selector but I am not able to scrape the content value within this tag. For example, if I want to get the UPC, I got an empty text in my scraping result.

To scrape the UPC the selector will be - meta[property=“og:upc”]
And then the attribute name will be - content

To give you more details, it’s important to use double-quote ("") in the attribute selector when there is a special character in the attribute value you are using in your selector.

For example, if your HTML was like this -

<meta xmlns:og="" property="upc" content="2633" />

This selector will work to extract this hidden value without double quotes as well -


But if the property value has a special character like “:” as in your case it’s “og:upc”. So, it must be enclosed with quotes to make your selector valid and scrape these hidden elements in meta tags.

<meta xmlns:og="" property="og:upc" content="2633" />

So, the valid selector is:
