元素定位练习 · 标签名定位
练习 By.TAG_NAME 的 Selenium 定位方法 — 独立专项练习页
作业说明
本次作业练习 Selenium By.TAG_NAME 定位：TAG_NAME 返回同名标签列表，适合遍历表格 tr/td、批量操作 button 等场景。请完成以下练习，理解标签定位的适用场景。
方法 4：By.TAG_NAME — 通过标签名定位
TAG_NAME 返回所有同名标签，适合遍历表格 tr/td、图片列表 img、超链接 a 等。
练习目标 1：统计页面所有图片并读取 alt 属性

定位后操作效果展示区域
本区域用于展示：使用 By.TAG_NAME（img / tr / td 等）定位到一组标签后，执行批量读取 / 点击 / 统计等操作的反馈。
当前尚无操作记录
请尝试：① 点击上方任意风景图片（查看 alt） ② 点击学生表格任意行（查看该行内容） ③ 统计表格里的总条数。
操作日志（点击/输入后记录在此）
本日志仅展示效果，方便你在 Selenium 脚本里用 By.ID, "action-log" 读取后断言操作是否成功执行。
[等待操作] 暂无任何交互，欢迎开始练习……
