Software for web scraping

[NewbieD]

I would like to build a feed through which helps me gather company specific data from a diverse set of sites.

 

I.e. I'd like to filter a set of sites (some examples: stamdata.com, https://marknadssok.fi.se/publiceringsklient, some twitter searches, etc) based on company name and have any hits show up in my feed. I'd like these to be polled regularly.

 

Any suggestions for software to set something like this up without learning some web scraping APIs?
