如何从 mediawiki 中提取纯文本？
How to extract plain text from mediawiki?
我已经从 https://awoiaf.westeros.org/index.php/Special:Export. They come in XML format. I would like plain text from the "Synopsis" sections. You can download the whole thing here 导出了一些类别（压缩后 54KB）。
典型的概要部分如下所示：
==Synopsis== [[Catelyn Tully|Catelyn]] listens to the continuous pounding noise of the drums the musicians in the hall are playing. She
is seated between [[Ryman Frey]] and [[Roose Bolton]] during the
wedding feast. She remarks to herself how joyless the wedding is, and
watches as [[Robb Stark|Robb]] dances with several of the Frey maids
and [[Edmure Tully|Edmure]] dotes on his soon to be wife, [[Roslin
Frey|Roslin]]. Catelyn becomes more wary when she learns that [[Olyvar
Frey|Olyvar]], [[Perwyn Frey|Perwyn]], and [[Alesander Frey]] are all
not in attendance at the wedding. She notices [[Merrett Frey]] trying
to drink the [[Greatjon Umber|Greatjon]] under the table, and finally
Lord [[Walder Frey]] calls for the bedding. Robb does not participate
as the Greatjon carries a weeping Roslin to the bed chamber.
如何从所有概要部分中提取纯文本？
首先，您需要将其解析为XML。我推荐使用 lxml 和 xpath。
from lxml import etree
tree = etree.parse('file.xml')
expression = '/m:mediawiki/m:page/m:revision/m:text/text()'
namespaces = {"m": "http://www.mediawiki.org/xml/export-0.10/"}
texts = tree.xpath(expression, namespaces=namespaces)
获得所有文本部分后，使用正则表达式逐一解析。或者编写自己的解析器。
