inserting newlines in xml file generated via xml.etree.ElementTree in python

Question

I have created a xml file using xml.etree.ElementTree in python. I then use

tree.write(filename, "UTF-8") 

to write out the documen

Answer 1

There is no pretty printing support in ElementTree, but you can utilize other XML modules.

For example, xml.dom.minidom.Node.toprettyxml():

Node.toprettyxml([indent=""[, newl=""[, encoding=""]]])

Return a pretty-printed version of the document. indent specifies the indentation string and defaults to a tabulator; newl specifies the string emitted at the end of each line and defaults to \n.

Use indent and newl to fit your requirements.

An example, using the default formatting characters:

>>> from xml.dom import minidom
>>> from xml.etree import ElementTree
>>> tree1=ElementTree.XML('12')
>>> ElementTree.tostring(tree1)
'12'
>>> print minidom.parseString(ElementTree.tostring(tree1)).toprettyxml()
