回答1:

I checked the documentation and found no reference for single/double-quote option.

I think your only recourse is print etree.tostring(n).replace('"', "'")

Update

Given:

from lxml import etree
n = etree.Element('test')
n.set('id', "Zach's not-so-good answer")

my original answer could output malformed XML because of unbalanced apostrophes:

<test id='Zach's not-so-good answer'></test>

Martijn suggested print etree.tostring(n).replace("'", ''').replace('"', "'") to address the problem:

<test id='Zach&apos;s not-so-good answer'></test>
