ET.fromstring gives ParseError

I am trying to parse an xml string and I want just the PackageReference Include attribute details and the Version of it. When I say ET.fromstring(xml) it gives error like xml.etree.ElementTree.ParseError: not well-formed (invalid token): line 284, column 84. I verified if the xml is valid on multiple websites and there seems to be no issues with my xml and it is well formed. Please see my Edit below.

xml parse error

    import xml.etree.ElementTree as ET
    
    thisDict={}
    
    def parseXMLInCsProj(xml):
      tree = ET.fromstring(xml)
      for packageReference in tree.findall('.//PackageReference'):
         if packageReference is None:
            continue
         if 'Include' in packageReference:
            key=packageReference.get('Include')
         child_item=packageReference.find('.//Version').text
         thisDict[key]=child_item

EDIT: As suggested I updated my xml string. Now I don't see the error. But as soon as the debugger comes to the line for packageReference in tree.findall('.//PackageReference'):, the program terminates. Please help.

Prop `className` did not match in next js app

I have written a sample code ( Github Link here ). this is a simple next js app, but giving me error when I refresh the page. This seems to be the common problem and I tried the fix provided in the internet but does not seem to fix my issue. The error is Warning: Prop className did not match. Server: "MuiBox-root MuiBox-root-1" Client: "MuiBox-root MuiBox-root-2". Did changes for _document.js, modified _app.js as mentioned in official website and solutions in stackoverflow. but nothing seems to work. Could someone take a look and help me whats wrong with the code? Via Active questions tagged javascript - Stack Overflow https://ift.tt/2FdjaAW
