Is your feature request related to a problem? Please describe.
I want an easy way to scrape a website and retrieve information that isn't in a table, but still can be returned in a tabular format.

Describe the solution you'd like
I would like to be able to write the following query to retrieve prices on pages like the Ebay Deals page.

SELECT 
    '.dne-itemtile-detail span[class^="ebayui-ellipsis"]' as product,
    '.dne-itemtile-detail .dne-itemtile-price span.first' as price
FROM "https://www.ebay.com/deals/"
