[FIXED] How do I change the text of multiple elements with the same name in elementtree

Issue

So I have an XML which has a line:

<factor-apply>1.2</factor-apply>

And this line is in my XML twice.

I would like to change the text for both lines such that they both change to:

<factor-apply>0.5</factor-apply>

My code is as follows:

import xml.etree.ElementTree as ET
xml_tree = ET.parse(TestXML.xml)
root = xml_tree.getroot()
root.find(".//{*}factor-apply").text = "0.5" 
ET.tostring(root)

Now this changes the first factor line in my XML but not the second.

I tried to do

root.findall(".//{*}factor-apply").text = "0.5"

but I get the error message

AttributeError                            Traceback (most recent call last)
~\AppData\Local\Temp\ipykernel_5072\1499665917.py in <module>
      3 xml_tree = ET.parse(TestXML.xml)
      4 root = xml_tree.getroot()
----> 5 root.findall(".//{*}factor-apply").text = "0.5" 
      6 ET.tostring(root)

AttributeError: 'list' object has no attribute 'text'

I'm wondering if I would have to make a loop in order to this as findall isn't working?? Any suggestions would be appreciated.

I would like to be able to do this for any variable. So I have a line which corresponds to date of birth. But that line is there 10 times so I would want to change all 10 lines for example

Solution

Try something like

for factor in root.findall(".//{*}factor"):
     factor.text = "0.5" 

and see if it works. If it does, you can probably replace factor with any other element name.
