我有一个SGML格式的528k文档列表，其中一个文档的示例如下：

我想在<TEXT></TEXT>之间提取palin文本，想要的结果如下：

17 June 1994

Python/Java 中是否有允许这样做的库或工具？

Answer 1

您可以在 python

中使用 BeautifulSoup

我尝试了这段代码并获得了所需的输出。

from bs4 import BeautifulSoup
with open('file.txt','r') as fo:
    sgml=fo.read()
soup = BeautifulSoup(sgml,'html.parser')
text_list=soup.find_all('text')
for item in text_list:
    lines_in_item=item.text.split('\n')
    [print(x.strip()) for x in lines_in_item if x.strip()!=""]

输出

1993
17 June 1994
Arms, Military Equipment
