I want to add doctypes to my XML documents that I'm generating with LXML's etree.
However I cannot figure out how to add a doctype. Hardcoding and concating the string is not an option.
I was expecting something along the lines of how PI's are added in etree:
pi = etree.PI(...)
doc.addprevious(pi)
But it's not working for me. How to add a to a xml document with lxml?

Parsing from strings and files. lxml. etree supports parsing XML in a number of ways and from all important sources, namely strings, files, URLs (http/ftp) and file-like objects. The main parse functions are fromstring() and parse(), both called with the source as first argument.
Introduction. The lxml XML toolkit is a Pythonic binding for the C libraries libxml2 and libxslt. It is unique in that it combines the speed and XML feature completeness of these libraries with the simplicity of a native Python API, mostly compatible but superior to the well-known ElementTree API.
lxml is a Python library which allows for easy handling of XML and HTML files, and can also be used for web scraping. There are a lot of off-the-shelf XML parsers out there, but for better results, developers sometimes prefer to write their own XML and HTML parsers. This is when the lxml library comes to play.
This worked for me:
print etree.tostring(tree, pretty_print=True, xml_declaration=True, encoding="UTF-8", doctype="<!DOCTYPE TEST_FILE>")
