Changing the default indentation of etree.tostring in lxml
Since version 4.5, you can set indent size using indent()
function.
etree.indent(root, space=" ")
print(etree.tostring(root))
As said in this thread, there is no real way to change the indent of the lxml.etree.tostring
pretty-print.
But, you can:
- add a XSLT transform to change the indent
- add whitespace to the tree, with something like in the cElementTree library
code:
def indent(elem, level=0):
i = "\n" + level*" "
if len(elem):
if not elem.text or not elem.text.strip():
elem.text = i + " "
if not elem.tail or not elem.tail.strip():
elem.tail = i
for elem in elem:
indent(elem, level+1)
if not elem.tail or not elem.tail.strip():
elem.tail = i
else:
if level and (not elem.tail or not elem.tail.strip()):
elem.tail = i
