            a.preventDefault();
        },
        error: function (err) {
        }
    });
}

我如何获得前两个段落标记之间的字符串？然后，我如何获得第2段标记之间的字符串？

Answer 1

Regular expressions

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

在<p>和</p>

之间

In [7]: content = "<p>I'd like to find the string between the two paragraph tags.</p><br><p>And also this string</p>"

In [8]: re.findall(r'<p>(.+?)</p>', content)
Out[8]: 
["I'd like to find the string between the two paragraph tags.",
 'And also this string']

Answer 3

如果您想要p标签之间的字符串（不包含p标签），请在findall方法

中在。+？中添加括号。

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']

获取两个字符串之间的字符
