我想将HTML输出（人们在浏览器上看到的内容）转换为String（实际上可能是一组字符串）

<!DOCTYPE html>
<html lang="en">

    <meta charset="UTF-8">
    <title>Title</title>

尽管有如此多的代码，但是当您运行该片段时，您实际上会将文本视为“音量”“1”“US Tablespoon”“=”“3”“US Teaspoon”

我搜索的算法只能从这样的HTML代码返回这些文本，是否可能？

Answer 1

当然，如果您使用类似Python BeautifulSoup的内容，您只需将文档加载到其中并输出文本。

#!/usr/bin/env python3
from bs4 import BeautifulSoup


html_doc = """
    your HTML string
"""

soup = BeautifulSoup(html_doc, 'lxml')
print(soup.get_text())

将HTML输出转换为String
