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？

f12 打开控制台直接贴进去
```javascript let content = ""; (function get_content(node) { for (child of node.children) { if (child.nodeName == "STRONG") { content += child.innerText + "\n"; } get_content(child); } })(document.body) console.log(content); ``` |

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') |
