Python pretty print an XML given an XML string
Here's how to parse from a text string to the lxml structured data type.
Python 2:
from lxml import etree
xml_str = "<parent><child>text</child><child>other text</child></parent>"
root = etree.fromstring(xml_str)
print etree.tostring(root, pretty_print=True)
Python 3:
from lxml import etree
xml_str = "<parent><child>text</child><child>other text</child></parent>"
root = etree.fromstring(xml_str)
print(etree.tostring(root, pretty_print=True).decode())
Outputs:
<parent>
<child>text</child>
<child>other text</child>
</parent>
I use the lxml library, and there it's as simple as
>>> print(etree.tostring(root, pretty_print=True))
You can do that operation using any etree
, which you can either generate programmatically, or read from a file.
If you're using the DOM from PyXML, it's
import xml.dom.ext
xml.dom.ext.PrettyPrint(doc)
That prints to the standard output, unless you specify an alternate stream.

To directly use the minidom, you want to use the toprettyxml()
function.
