Web Scraping project

[Epulone]

I would like find a way to learn to create a prog/script that:

1) open a specific web page 

2) analyse the content and extract specific parameters (example: object, price, description etc...)

3) and every x minutes check (comparing with the previous parameters) if there are new adds or some change has been applied and if yes send an email alert with the new parameters.

 

I am sure it is not easy  and considering I am not an expert what way do you suggest me to start and learn how to do it?

 

Thanks

What browser are you going to use? If IE, use the _IE* functions. If something else, use the webdriver UDF or the UIA UDF.

Best approach, take each of your requirements, and find the best way of doing each one individually and then combine them into the final script.

...just for the record, the good webdriver UDF can also be used with IE

I'd like to chime in - does the site have an API you can use? If yes, use that before you screen scrape.

Good thing to know, thanks. I don't do anything with browser automation myself so just throwing them out there. 🙄
