IP 2.7.1 xml.etree.Elementree#iterparse is not working

[ironpythonbot]

from StringIO import StringIO as S
from xml.etree import ElementTree as ET
ET.iterparse(S(''))
-->
AttributeError: TreeBuilder instance has no attribute '_parser'

Seems that SimpleXMLTreeBuilder.TreeBuilder or xmllib.XMLParser should have
this for iterparser to work (or the sys.platform == 'cli' part should be
changed in ElementTree.py).

Anyway completely makes it impossible to use iterparse in xml.etree with
ironpython.

It is somewhat weird that this is broken because nowadays IronPython ought to contain a working elementtree implementation [1] that is also available at [2]. What is really weird that this module works fine if I install it separately.

It turns out that iterparse is closely tied to the expat-based XML reader. Once
http://ironpython.codeplex.com/workitem/20023 is fixed then this one can be as well.

I improved the error message in 7f9fc2a.
