# xpath
# 绝对定位（/开头  非常依赖于页面顺序和位置）
# 相对定位 （//开头 不依赖页面顺序和位置）
# //标签名[@属性=值] 可附加逻辑运算符
# //input[@name="phone" and @datatype="m"]
# 层级定位 //div[@id="u1"//input[@name="phone"]   //div[@id="u1"/input[@name="phone"]
# 函数定位  text()  contains(@属性/text(), 值)  //a[text()="资料"] //a[contains(text(),"xxx")]
# 轴定位 ancestor祖先 parent父辈 preceding兄弟节点 preceding-sibling 前面的兄弟节点 following后面的节点  following-sibling节点之后的兄弟节点
# /轴名称::节点名称[@属性=值] //div//td/preceding::td

# css
