    我并不是个程序员 但是有有个这样的需求
    一个网页中都是这样的代码
    <li><strong>Fader</strong> — A sliding potentiometer control used in mixers and other processors.</li>
    我想把<strong>Fader</strong>中的“fader”字符提取出来并生成 TXT 文件
    请问怎么写呢?

    bs4,re,xpath 都可以实现需求。
    xpath 插件:
    chrome:xpath helper (好久没用了,不晓得现在功效如何)
    firefox:ChroPath (根据页面介绍自己配置下,很 ok 。)

    可以使用 selenium 库,再下载一个 Chrome 驱动(要和当前 google 浏览器版本一致

    命名为:strong.py

    from selenium import webdriver
    import os
    os.chdir('E:\\strong')

    wb = webdriver.Chrome()

    wb.get('https://www.soundonsound.com/sound-advice/glossary-technical-terms?amp')


    elements = wb.find_elements_by_tag_name('strong')

    for element in elements:
    print(element.text)


    在终端输入:python strong.py > output.txt # 将输出重定向到 txt

    想了一下,在 with 里直接用 for 循环将元素内容直接添加到一个 txt 文件更好,不用再重定向了
    from selenium import webdriver
    import os
    os.chdir('E:\\strong')

    wb = webdriver.Chrome()

    wb.get('网址')


    filename = 'a.txt'
    with open(filename,'w') as web_strong:
    elements = wb.find_elements_by_tag_name('strong')
    for element in elements:
    web_strong.write(element.text + '\n')
