If you want to generate random XML, don't use the HTML sub-module of lxml.
Its a specific sub-set of functionality for HTML only documents.

>>> from lxml.builder import ElementMaker
>>> from lxml import etree
>>> E = ElementMaker()
>>> html = E.html(
...     E.form(
...             E.input(type="text", name="email"),
...             E.input(type="text", name="blah")
...     )
... )
>>> etree.tostring(html)
'<html><form><input type="text" name="email"/><input type="text"
name="blah"/></form></html>'
