Answer 1

常用表达

import re
matches = re.findall(r'<p>.+?</p>',string)

以下是您在控制台中运行的文本。

 >>>import re
>>>string = """<p>I'd like to find the string between the two paragraph tags.</p><br><p>And also this string</p>"""
>>>re.findall('<p>.+?</p>',string)
["<p>I'd like to find the string between the two paragraph tags.</p>", '<p>And also this string</p>']

Answer 2

如果你想要 p 标签之间的字符串（ 不包括 p 标签）然后添加括号到 .+? 在 findall 方法中

import re
    string = """<p>I'd like to find the string between the two paragraph tags.</p><br><p>And also this string</p>"""
    subStr = re.findall(r'<p>(.+?)</p>',string)
    print subStr

结果

["I'd like to find the string between the two paragraph tags.", 'And also this string']
