I work for a sailing school that owns a database with questions.
The questions are obtained from the official examination test centers as pdf documents and the passed onto our database.
There are different examination centers across the country and normally every time a new test takes place on their city, the exam is uploaded by each organization to their own website and made public.
In order for me to be aware when a new pdf file has been uploaded to one of those websites I was wondering if there is a way to monitor them like checking for link updates ( assuming the links will always be on the same place of the website )or comparing a website structure using timestamps to trigger an alarm like when those timestamps don’t match ( l assuming there has been an update with that comparison )
I don’t know if I made myself understood or if it is doable at all.
Many thanks for your patience.
