getting error encoded' pseudo-class 暂时没有用美汤实现

Getting error encoded' pseudo-class is not implemented at this time with beautiful soup

我正在尝试提取 content:encoded 标签中的 table 元素,同时使用 pythons beautiful soup 提取 XML 文件的内容。

出现以下错误

An error occurred  ':encoded' pseudo-class is not implemented at this time

查看下面我的代码

import bs4

content_html_list = []


def main():
    try:
       #first get the xml file content and pass it to string variable called "res_text"
        soup = bs4.BeautifulSoup(res_text, features="xml")

        content_html_tag_list = soup.select('content:encoded')
        for content_htmls in content_html_tag_list:
            content_html = content_htmls.text
            content_html_list.append(content_html)

        print(f"content_html_list 0 is, {len(content_html_list)}")

        print(f"content_html_list = , {content_html_list}")

    except Exception as e:
        print(f'An error occurred  {str(e)}')


main()

见下文xml

请指教提取文本的最佳方法

转义 : 使其不被视为 pseudo-class 并使用解析器 'lxml'

soup.select('content\:encoded')
