New submission from yucheng chen <[email protected]>:
issue8277
It couldn't work for those comments before the root element.
It will raise an error that "xml.etree.ElementTree.ParseError: multiple
elements on top level".
Example:
test.xml
--------
<?xml version="1.0" encoding="utf-8"?>
<!-- comments here doesn't work -->
<root node>
<nodeA />
<!-- comments here is ok -->
<nodeB />
</root node>
test.py
-------
from xml.etree import ElementTree
class MyTreeBuilder(ElementTree.TreeBuilder):
def comment(self, data):
self.start(ElementTree.Comment, {})
self.data(data)
self.end(ElementTree.Comment)
with open('c:/temp/t.xml', 'r') as f:
xml = ElementTree.parse(
f, parser=ElementTree.XMLParser(target=MyTreeBuilder()))
ElementTree.dump(xml)
