    44Dependencies 
    55------------ 
     6   At least one of these XML processing libraries is required : 
     7 
    68   cElementTree 1.0.6 or plain Elementree 1.3 
    79 
    …… 
    1214       Documentation: http://effbot.org/zone/elementtree-13-intro.htm 
    1315 
    14    lxml is also needed to run the tests. 
     16   lxml >= 2.2.2. Details: 
     17       Tested versions of the lxml package so far 
     18           - on lxml 2.1.2 (MacOSX build by plone buildout recipe) -> fails 
     19       - on lxml 2.2.2 (homemade build on Ubuntu 9.04) -> works 
     20       The discriminating issue between those versions is the following: 
     21          http://osdir.com/ml/python.lxml.devel/2006-06/msg00084.html 
     22 
     23       Run the unit tests to know if your version works, and don't 
     24       hesitate to report the results 
     25 
     26Testing dependencies 
     27-------------------- 
     28   The tests currently try and load all possible engines. Therefore, 
     29   you'll need to have both (c)ElementTree and lxml to run them. 
     30   This could be lifted in the future. 
     31 
     32   Even if you deactivate the testing of lxml engines, lxml will still 
     33   be required, because it's been used by the testing infrastructure 
     34   itself (to check the output produced by the tested engine) 
     35

    1637Installing 
    …… 
    4263  --------------------- 
    4364  All engine tests are ran for all engines. 
    44   The lxml engine doesn't work yet, isn't hooked by default, and fails 
    45   on some tests. 
    4665 
    4766  lxml is also needed to run the doctests, but this has nothing to do
