Gather Data from a Public Website

Hello

I need assitance extracting 1) email addresses and 2) Postal Addresses of all members of this directory:

https://yellow.local.ch/q?browse=all-restaurants&where=

Can you build a simple algorithm that pulls all of the info from each restaurant's info page, for example:

This entry shows the postal address and email address:
--> https://yellow.local.ch/de/d/Zizers/7205/Hotel/Hotel-Sportcenter-Fuenf-Doerfer-AG-stRJm03qNycdv_UTBF_exA

however, this entry shows the postal address and the website, and in a second stage we would need to go further to identify the email address from the website:
--> https://yellow.local.ch/de/d/Zuerich/8006/Restaurant/Casa-Ferlin-GXvPAor1ifNfpF0U5PTG0w
