lxml / BeautifulSoup parser warning

[alessandrogreco10]

When trying to run the following:

morningscraper.get_data(isin[0]) where isin is a isin code (string) vector

I get this error

To get rid of this warning, change code that looks like this: BeautifulSoup(YOUR_MARKUP}) to this: BeautifulSoup(YOUR_MARKUP, "lxml") markup_type=markup_type))

How should I fix the problem? what and most importantly where should I replace it ?
