Read, Modify the xml save it in a new xml using python

Question

Below are the steps I am following:

1. Reading the xml file as dictionary

   import xmltodict
   
   with open("example.xml") as sxml:
       data = xmltodict.parse(sxml.read())
   

2. Changing the value

   data["key"]["key1"] = "some value"
   

3. I want to save the changes in example.xml file or I want to create a new file and save the changes.

How can I do it?

Answer 1

Following README we can simply do

with open('example.xml', 'w') as result_file:
    result_file.write(xmltodict.unparse(data))

if you want to overwrite example.xml OR

with open('result.xml', 'w') as result_file:
    result_file.write(xmltodict.unparse(data))

if you want to create new file result.xml.

Answer 2

Simple answer:

from lxml import etree

with open('yourxmlfile.xml', encoding='utf8') as inputfile:
    contents = inputfile.read()
parser = etree.XMLParser(strip_cdata=False)
tree = etree.XML(contents, parser)
root = tree
#make some edits to root here
with open('yourxmloutput.xml', 'w', encoding='utf8') as outfile:
    outfile.write(etree.tostring(root))
