how to remove attribute of a etree Element?


I’ve Element of etree having some attributes – how can we delete the attribute of perticular etree Element.

Asked By: shahjapan



The .attrib member of the element object contains the dict of attributes – you can use .pop("key") or del like you would on any other dict to remove a key-val pair.

Example :

>>> from lxml import etree 
>>> from lxml.builder import E
>>> otree = E.div()
>>> otree.set("id","123")
>>> otree.set("data","321")
>>> etree.tostring(otree)
'<div id="123" data="321"/>'
>>> del otree.attrib["data"]
>>> etree.tostring(otree)
'<div id="123"/>'

Take care sometimes you dont have the attribute:

It is always suggested that we handle exceptions.

    del myElement.attrib["myAttr"]
except KeyError:

You do not need to try/except while you are popping a key which is unavailable. Here is how you can do this.


import xml.etree.ElementTree as ET

tree = ET.parse(file_path)
root = tree.getroot()      

print(root.attrib)  # {'xyz': '123'}

root.attrib.pop("xyz", None)  # None is to not raise an exception if xyz does not exist

print(root.attrib)  # {}
