如何在Python中的特定单词后删除部分字符串

Question

我将API响应作为字符串获取，可以采用两种不同的格式：

1）This is a message. <br><br>This message was created by Jimmy.

2）

This is a message.

Text can be in the new row.

This message was created by Jimmy.

我想删除文本“此消息是由['name']”从每条消息创建的。预期结果：

  

这是一条消息。

这是我尝试过的：
modified_message = re.search('(.+?)<br><br>', message).group(1)

它适用于1）示例，但当然不适用于2）。

我如何从2）示例中过滤掉文本，因为它是多行字符串，或者是否可以使用一个表达式？

Answer 1

请检查一下。 添加了处理多行字符串的代码。

import re
data1 = "This is a message. <br><br>This message was created by Jimmy."
data2 = """
This is a message.

This message was created by Jimmy.
"""
print "First case..."
print data1
output1 = re.findall('(.*?)This message was created',data1,re.DOTALL)[0].replace("<br>",'')
print "Output is ..."
print(output1)
print "----------------------------------------"
print "Second Case..."
print data2
print "Output is ..."
output2 = re.findall('(.*?)This message was created',data1,re.DOTALL)[0].replace("<br>",'')
print(output2)

输出：

C:\Users>python main.py
First case...
This is a message. <br><br>This message was created by Jimmy.
Output is ...
This is a message.
----------------------------------------
Second Case...

This is a message.

This message was created by Jimmy.

Output is ...

This is a message.
