python-3.x - 用文本替换 html 文件中的表格......（例如@@##这里有一个表格）

问题描述

我正在使用 beautifulsoup 从 python 中的 html 文件中提取文本。我想提取所有文本数据并丢弃表格。但是我们可以做些什么来用文本替换 html 中的表格（例如“@@##这里有一个表格@@##”）

我能够使用 beautifulsoup 读取 html 文件并删除了 table uisng strip_tables(html)。但不确定如何删除表格并替换为指定表格的文本。

def strip_tables(soup):
    """Removes all tables from the soup object."""
    for script in soup(["table"]): 
        script.extract()
    return soup

sample_html_file = "/Path/file.html"
html = read_from_file(sample_html_file) 
# This function reads the file and returns a file handle for beautifulsoup
soup = BeautifulSoup(html, "lxml")
my_text = strip_tables( soup ).text

这是带有表格的 html 文件：

这是 strip_tables 之后的数据：

预期结果

解决方案

请尝试在 strip_tables 函数中replaceWith()使用。extract()希望对您有所帮助。

def strip_tables(soup):
    """Removes all tables from the soup object."""
    for script in soup(["table"]): 
        script.replaceWith(" @@## There was a table here @@## ")
