xml.etree.ElementTree.ParseError：文档元素后出现垃圾

Question

I'm trying to install CESM2 and while trying to create a new case I receive this error:

 File "/usr/lib64/python3.6/xml/etree/ElementTree.py", line 1196, in parse tree.parse(source, parser) File "/usr/lib64/python3.6/xml/etree/ElementTree.py", line 597, in parse self._root = parser._parse_whole(source) xml.etree.ElementTree.ParseError: junk after document element: line 211, column 2

When I traced back line 211 in ElementTree.py, it contains this function:

def __bool__(self):
    warnings.warn(
        "The behavior of this method will change in future versions.  "
        "Use specific 'len(elem)' or 'elem is not None' test instead.",
        FutureWarning, stacklevel=2
        )
    return len(self._children) != 0 # emulate old behaviour, for now

Can anyone please suggest how to resolve this?

Answer 1

The indicated position ( line 211, column 2 ) refers to the source file being parsed, not the line in your code.

When parsing XML file, it should contain a single element at the top level. Apparently your source XML is malformed.

Sometimes a solution in this case is to "wrap" the whole content with a single "root" element. At least this parsing error should disappear, but note that it changes the output XML tree, compared to the original intention, so maybe some XPath expressions should be also changed.
