Describe the problem.
Hello, I am currently trying to scrape a news website -each element contains a few items such as county, source and deal value - the problem is that they not present in all articles - which leads to them being a different 'nth of type (n)' each time. The only way of recognising these text is the text preceding the actual text I want. Is there a way to only scrape the data if it contains "Source" for instance? Thanks

Url: Media mergers news: Tracker on all latest news media M&A (pressgazette.co.uk)


The ideal output is 4 columns - source, deal value, country and status - each with the text inside associated with the correct category (i.e source, country) Thank you!
