Help for task on Chrome

Hello.I want to create a macro with web automation (i am not sure if desktop automation needed also).
Here is what i mean.
At first we say to Kantu to select a window of Chrome where appears temperatures of cities.Then i need somehow to say "If temperature value for London is greater than 25 degrees then select Gmail tab of Chrome and send email to a specific contact and with specific title “Temperature in London is above 26 degrees” or "Temperature in London is 28 degrees " (or what ever the temperature is) .Is this possible please? Thanks.

Hi @Panos. I would assume this is a duplicate of How to fill different numbers.
