I want to remove an element from etree,how to do it? Here's the code

from lxml import etree
root = etree.parse(open("Sample.xml",'r'))
for e in root.iter():
  if(some condition):
     root.remove(e)

the above code gives me AttributeError: 'lxml.etree._ElementTree' object has no attribute 'remove'. is there any other way to remove the element?

result of dir(etree)

Maybe e.getparent().remove(e)?

  • Some information about how `ElementTree.iter` works and that `remove` can only be used on child elements may make this answer more complete, but I'm not sure it's necessary since this is a duplicate. – Jared Goguen Jun 28 '16 at 13:45
