[lxml-dev] could not find doctest

Wed May 20 20:06:36 CEST 2009

I discovered the following for my purpose:
---------------------------------------
import lxml.html

## html output
html = lxml.html.fromstring('''\
      <html><body onload="" color="white">
Creating HTML with the E-factory
      <p>Hi !</p>
      </body></html>
      ''')
print lxml.html.tostring(html)
#<html><body onload="" color="white"><p>Hi !</p></body></html>

print lxml.html.tostring(html)
from lxml.html import builder as E
html = E.HTML(
    E.HEAD(
#     E.LINK(rel="stylesheet", href="great.css", type="text/css"),
      E.TITLE("Best Page Ever")
    ),
    E.BODY(
      E.H1(E.CLASS("heading"), "Top News"),
      E.P("World News only on this page", style="font-size: 200%"),
      "Ah, and here's some more text, by the way.",
      lxml.html.fromstring("<p> and this is a parsed fragment </p>")
    )
  )

print lxml.html.tostring(html,pretty_print=True) <-- is what I want
------------------------------------------
but got confused by doctest yesterday, being new to python.
