json_2">一、获取特定文本和json链接

python">from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# 指定 Chrome 驱动程序路径
chrome_driver_path = r'F:\chrome-win64\chromedriver.exe'

# 创建 Chrome 浏览器的 WebDriver 实例
driver = webdriver.Chrome(executable_path=chrome_driver_path)

# 访问网页
url = "动态网页网址链接"
driver.get(url)

# 等待页面加载完成
driver.implicitly_wait(3)

# 使用显示等待，等待姓名元素出现
wait = WebDriverWait(driver, 10)  # 最长等待时间为10秒

for i in range(1, 100):
    name_xpath = f"/html/body/div[5]/ul[1]/li[{i}]/p/a"

    # 等待姓名元素出现
    name_element = wait.until(EC.visibility_of_element_located((By.XPATH, name_xpath)))

    name = name_element.text
    link = name_element.get_attribute("href")
    print(f"姓名: {name}, 链接: {link}")

# 关闭浏览器
driver.quit()

结果：现TXT文本内容

姓名：abc，链接：http://abc.json

二、打开现TXT文本，将姓名保留，把获得的新链接放入姓名之后，以新的文本输出

                else:

            # 写入姓名和邮箱地址到文件
            output_file.write(f'{name}: {email}\n')
        except Exception as e:
            print(f"打开链接失败: {e}")

# 关闭浏览器

结果：现TXT个人网址文本内容
