Extract values from xml in column

If I save the xml as a file and add it as a data source, then yes i can eventually drill down to the right level.  The problem is the xml is stored in a text field, so I can't get it to recognize it.  Even when I use the xml file i can only drill down to the right level of data in the Data screen - not in the Report screen.

The xml comes from a repeating section in a Nintex Form I built in Sharepoint.  XML is the only way I can access that info, so I was able to get it displayed in a column in Sharepoint.  I'm definitley very new to PowerBI, so not really sure how else to get to the data.  Utlimately I just want to be able to show all the data in the XML somehow on a report/dashboard.
