It seems like this is do-able but I don't know what tools would work best. I have a feature service of Parcel data that includes a parcel PIN. Each parcel has a corresponding web page that can be accessed by appending the PIN to a static url. Once you're on that page there is a plethora of additional information in tables. I would like to be able to extract this info and append it to my feature service.
For example, I would like each parcel to include the Owner name in the Pop-up. Owner name is listed on the webpage, so I should be able to scrape it somehow. Ideally a solution would do this using Arcade in the Pop-up so it's always correct, but I would be fine with running a tool ever so often.
Is there a way to do this in ArcGIS Online, or with some other open source tool that is more simple than, "build a web scraper?"
