私はxml解析とPythonが初めてなので、ご容赦ください。lxml を使用して wiki ダンプを解析していますが、各ページ、そのタイトル、およびテキストだけが必要です。
今のところ、私はこれを持っています：
from xml.etree import ElementTree as etree
def parser(file_name):
document = etree.parse(file_name)
titles = document.findall('.//title')
print titles
現時点では、タイトルは何も返していません。ElementTree findall() return empty listと lxml documentation のような以前の回答を見てきましたが、ほとんどのものは HTML の解析に合わせて調整されているようです。
これは私の XML のセクションです。

<text xml:space="preserve" bytes="1436">'''Aratrum''' is the Latin word for [[plough]], and "arotron" (αροτρον) is the [[Greek language|Greek]] word. The [[Ancient Greece|Greeks]] appear to have had diverse kinds of plough from the earliest historical records. [[Hesiod]] advised the farmer to have always two ploughs, so that if one broke the other might be ready for use. These ploughs should be of two kinds, the one called "autoguos" (αυτογυος, "self-limbed"), in which the plough-tail was of the same piece of timber as the share-beam and the pole; and the other called "pekton" (πηκτον, "fixed"), because in it, three parts, which were of three kinds of timber, were adjusted to one another, and fastened together by nails.
The ''autoguos'' plough was made from a [[sapling]] with two branches growing from its trunk in opposite directions. In ploughing, the trunk served as the pole, one of the two branches stood upwards and became the tail, and the other penetrated the ground and, sometimes shod with bronze or iron, acted as the [[ploughshare]].

また、 iterparse を試して、見つかった要素のタグを出力しました：
for e in etree.iterparse(file_name):
print e.tag
しかし、タグ属性がない e について不平を言っています。
