How to write xml file with multiple root element using ElementTree in python

Question

I have python script and I have already written logic of writing xml file using xml.etree.cElementTree and the logic is look like below

import xml.etree.cElementTree as ET

root = ET.Element("root")
for I in range(0,10):
    ET.SubElement(root, "field1").text = "some value1"
    ET.SubElement(root, "field2").text = "some vlaue2"

tree = ET.ElementTree(root)
tree.write("filename.xml")

and it give output like

<root>
      <field1>some value1</field1>
      <field2>some value2</field2>
      <field1>some value1</field1>
      <field2>some value2</field2>
      <field1>some value1</field1>
      <field2>some value2</field2>
      <field1>some value1</field1>
      <field2>some value2</field2>......
</root>

but I want to add multiple root and need out put like below

<root>
  <field1>some value1</field1>
  <field2>some value2</field2>
</root>
<root>
  <field1>some value1</field1>
  <field2>some value2</field2>
</root>
<root>
  <field1>some value1</field1>
  <field2>some value2</field2>
</root>
<root>
  <field1>some value1</field1>
  <field2>some value2</field2>
</root>

is it possible to write like above file using xml.etree.cElementTree in python

What you want to generate is not valid xml. See Do you always have to have a root node with xml/xsd? for more info.

Also you can always manually concatenate the string.

import xml.etree.cElementTree as ET
result= ''
for I in range(0, 10):
    root = ET.Element("root")
    ET.SubElement(root, "field1").text = "some value1"
    ET.SubElement(root, "field2").text = "some vlaue2"
    result += ET.tostring(root)
print(result) # or write the result to a file
