Receiving information from URL

Is there a way that I can copy a word or words from a URL in any given record and paste it into another field on the same table? If so, what would that script look like?

I have a table full of records each having their own link to a specific URL (none are the same). Each link opens up a specific record on another database made to match. Within each record in this linked database (which is not airtable btw) is a place called “Contractor or Supplier” about halfway down the page where, directly next to it, is the name of a contractor or supplier. I need to know if there is a way I can have it look in that link, grab the name of the contractor or supplier, and paste that name into a “Link to another record” field within the same table.
