如何获取html标记之间的空格

var htmlString = "<p>   This is a paragraph.   </p>";
var spaceRegex = /<[^>]+>(\s+)<[^>]+>/g;
var spaces = htmlString.match(spaceRegex);
console.log(spaces);

var htmlString = "<p>   This is a paragraph.   </p>";
var div = document.createElement('div');
div.innerHTML = htmlString;
var spaces = div.firstChild.textContent.trim();
console.log(spaces);

from bs4 import BeautifulSoup

htmlString = "<p>   This is a paragraph.   </p>"
soup = BeautifulSoup(htmlString, 'html.parser')
spaces = soup.p.string.strip()
print(spaces)
