example data processing warning using google colab

[amscosta]

Hello, The following warning is issued when processing one of the .xml from the example data: Processing: paperetl/file/data/0.xml /usr/local/lib/python3.10/dist-packages/paperetl/file/tei.py:35: XMLParsedAsHTMLWarning: It looks like you're parsing an XML document using an HTML parser. If this really is an HTML document (maybe it's XHTML?), you can ignore or filter this warning. If it's XML, you should know that using an XML parser will be more reliable. To parse this document as XML, make sure you have the lxml package installed, and pass the keyword argument features="xml" into the BeautifulSoup constructor. soup = BeautifulSoup(stream, "lxml")

Any clue how to avoid/correct that? Thanks a lot.
