regex - 正则表达式 |删除给定单词前多行的单词

Question

我从一个网站上抓取了几篇文章，现在我试图通过从抓取的文本中删除第一部分来使语料库更具可读性。应该删除的区间在标签<p>Advertisement内和最后的标签 </time>在文章开始之前。如您所见，正则表达式应该删除多行的几个单词。我尝试了 DOTALL 序列，但没有成功。

这是我的第一次尝试:

import re

text='''
<p>Advertisement</p>, <p class="byline-dateline"><span class="byline"itemprop="author creator" itemscope="" itemtype="http://schema.org/Person">By <span class="byline-author" 
data-byline-name="MILAN SCHREUER" itemprop="name">MILAN SCHREUER</span> and </span><span class="byline" 
itemid="http://topics.nytimes.com/top/reference/timestopics/people/r/alissa_johannsen_rubin/index.html" 
itemprop="author creator" itemscope="" itemtype="http://schema.org/Person"><a href="http://topics.nytimes.com/top/reference/timestopics/people/r/alissa_johannsen_rubin/index.html" 
title="More Articles by ALISSA J. RUBIN"><span class="byline-author" data-byline-name="ALISSA J. RUBIN" data-twitter-handle="Alissanyt" itemprop="name">ALISSA J. RUBIN</span></a></span><time class="dateline" content="2016-10-06T01:02:19-04:00" 
datetime="2016-10-06T01:02:19-04:00" itemprop="dateModified">OCT. 5, 2016</time>
</p>, <p class="story-body-text story-content" data-para-count="163" data-total-count="163">BRUSSELS — A man wounded two police officers with a knife in Brussels around noon on Wednesday in what the authorities called “a potential terrorist attack.”</p>, <p class="story-body-text story-content" 
data-para-count="231" data-total-count="394">The two officers were attacked on the Boulevard Lambermont in the Schaerbeek district, just north of the city center. A third police officer, who came to their aid, was also    injured. None of the three had life-threatening injuries.</p>
'''
my_pattern=("(.*)</time>") 
results= re.sub(my_pattern," ", text)
print(results)

Answer 1

试试这个:

my_pattern=("[\s\S]+\<\/time\>") 

如果您还想删除以下标签 </p> , 逗号 ,和空间，你可以使用这个:

my_pattern=("[\s\S]+\<\/time\>[\s\S]\<\/p\>\,\s")
