AI财务助手智能体技术详解：从概念到实战（2026年4月更新）

 传统RPA脚本：基于坐标和XPath定位
def bank_auto_download():
     登录网银
    driver.find_element_by_id("username").send_keys("admin")
    driver.find_element_by_id("password").send_keys("123456")
    
     点击“账户查询”按钮——坐标绑定，极易失效
    driver.find_element_by_xpath("/html/body/div[1]/div[2]/button").click()
    
     筛选日期——固定规则，无法处理非结构化数据
    driver.find_element_by_name("start_date").send_keys("2026-04-01")
    
     下载对账单——界面改版即崩溃
    driver.find_element_by_css_selector(".download-btn").click()
