如何在Scala类中漂亮地表示XML实体？

val xmlEntity = <person>
                  <name>John Doe</name>
                  <age>30</age>
                </person>

val name = xmlEntity \ "name" // 获取name子元素
val age = (xmlEntity \ "age").text.toInt // 获取age子元素的文本内容，并转换为整数类型

val complexXmlEntity = <person>
                         <name first="John" last="Doe">John Doe</name>
                         <age>30</age>
                         <address>
                           <street>123 Main St</street>
                           <city>New York</city>
                         </address>
                       </person>

xmlEntity match {
  case <person>{name @ <name>{firstName}</name>}</person> => println(s"First name: $firstName")
  case _ => println("Invalid XML entity")
}
