The following forum message was posted by richkatz at http://sourceforge.net/projects/pydev/forums/forum/293649/topic/4429027:

I have the same issue with PyDev (not related to Jython).  I have import lxml.etree
and I get  "Undefined variable from import: tostring"	  I'm using Python 2.7
using:

Window | Preferences | PyDev | Interpreter - Python
Libraries \System libs
C:\Python27\lib\site-packages\lxml-2.3-py2.7-win32.egg

And:
Project Properties DyDev - Interpreter/Grammer Python Grammar Version 2.7

I fixed it though by adding in etree.py as an external lib to the project, forcing
compilation, and then removing it.
