Python to update XML SubElement - emersonivo - Aug-01-2018 Hi all, I am looking for this help everywhere in the past days without success and I hope someone here can share some knowledge. In the XML data below, how do I do for: 1 - Update the {id="012345"/res name="attrib1"/last_seem key} 'date' and 'status' attributes? 2 - Delete the {id="012345"/res name="attrib2} 3 - Add a new {id="123456"/res name="attrib2"} with 'first_seem' and 'last_seem' keys and values Important: - I am going to have hundred different users/IDs - I am going to have dozens res/attributes <stop> <user id="012345"> <res name="attrib1"> <first_seem date="2018-07-31" status="REQUESTED">1</first_seem> <last_seem date="2018-07-31" status="INPROCESS">0</last_seem> </res> <res name="attrib2"> <first_seem date="2018-07-31" status="REQUESTED">1</first_seem> <last_seem date="2018-07-31" status="COMPLETED">0</last_seem> </res> </user> <user id="123456"> <res name="attrib1"> <first_seem date="2018-07-31" status="REQUESTED">1</first_seem> <last_seem date="2018-07-31" status="REQUESTED">0</last_seem> </res> </user> </stop> So far I found help to update values in a fixed path (i.e: /root/user/res/lastseem.text), what did not help me. I tried to use the same command used to create the XML above changing a single/desired value, but instead of update, Python created a new entry Thank you so much for any help.
