Python利用XPath的逻辑运算符实现多条件定位

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("https://example.com/login")

# 使用and组合条件
submit_btn = driver.find_element("xpath", '//button[@class="btn" and @type="submit"]')
submit_btn.click()

login_link = driver.find_element("xpath", '//a[contains(@class,"active") and text()="登录"]')

input_field = driver.find_element("xpath", '//input[@type="text" or @type="email"]')

save_element = driver.find_element("xpath", '//button[text()="保存"] | //a[contains(text(),"保存")]')

driver.get("https://www.baidu.com")

# 错误写法（易误解）：
# //input[@id and contains(text(),'搜索') or contains(@placeholder,'关键词')]
# 实际等价于: (@id and contains(text(),'搜索')) or contains(@placeholder,'关键词')

# 正确写法（按意图分组）：
search_box = driver.find_element("xpath", '//input[@id and (contains(text(),"搜索") or contains(@placeholder,"关键词"))]')

element = driver.find_element("xpath", '//*[@id and (@class="primary" or @type="submit")]')

# 匹配class包含"btn-"且id以"user_"开头的元素
elements = driver.find_elements("xpath", '//*[contains(@class,"btn-") and starts-with(@id,"user_")]')

# 定位所有可见的input元素（排除disabled的）
inputs = driver.find_elements("xpath", '//input[not(@disabled) and @type!="hidden"]')

from selenium import webdriver
from selenium.webdriver.common.by import By

driver = webdriver.Chrome()
driver.get("https://kyfw.12306.cn/otn/leftTicket/init")

# 定位出发站为"北京"且到达站为"上海"的日期选择器
date_input = driver.find_element(
    "xpath", 
    '//input[@id="date_range" and '
    '((@placeholder="出发日期" and ancestor::div[contains(@class,"from-station")]) or '
    '(@placeholder="到达日期" and ancestor::div[contains(@class,"to-station")]))]'
)
date_input.click()
