I do not know the structure of your webpage, but a way to extract all links of a webpage is by the following actions
- Launch <browser>
- Get details of web page (this will give a variable)
- Use that variable in Recognise entities in Text (select URL in dropdown)
But of course this is going to extract every single thing that looks like an URL eg; image links, etc.
Perhaps you can go from there as per your requirements.
