need some advice on editing scraped data

[bill]

Hello, I'd like some advice on the following complication:
I grab the data from a website the data is in the following format
proxy:port,http,randomnumber

I need to scrape the data and erase the ,http,randomnumber and output it to a text file every x minutes.

And what's the problem? You can take all lines one by one in loop and delete all unnecessary data from there with regexp

Or even better, create a regex to just grab the proxy:port from the DOM and put everything to a list.
