beautifulsoup featurenotfound lxml parser not installed error fails

Fixes BeautifulSoup raising FeatureNotFound when code asks for the lxml parser but lxml is not installed in the running environment. Use when html.parser works but lxml fails. Not for malformed HTML that parses but returns empty results.

Confirm the failing call passes lxml as the parser argument to BeautifulSoup.

Install lxml through the interpreter that runs the code, using python -m pip install lxml.

Rerun a small parse test on a short HTML string with the lxml parser.

If you cannot install packages in that environment, change the parser argument to html.parser and rerun.

Add lxml to your project requirements file and restart the app or notebook kernel.
