Faithfully Preserve Comments in Parsed XML

Question

I\'d like to preserve comments as faithfully as possible while manipulating XML.

I managed to preserve comments, but the contents are getting XML-escaped.

Looks like both answers from @Martin and @sukhbinder didn't work for me... So made this as a workable completed solution on python 3.x

from xml.etree import ElementTree

string = '''

    
    
        1
        2008
        141100
        
        
    
'''

class CommentedTreeBuilder(ElementTree.TreeBuilder):
    def comment(self, data):
        self.start(ElementTree.Comment, {})
        self.data(data)
        self.end(ElementTree.Comment)

parser = ElementTree.XMLParser(target=CommentedTreeBuilder())
tree = ElementTree.fromstring(string, parser)
print(tree.find("./*[0]").text)
# or ElementTree.parse(filename, parser)
