scala中xml修改元素详解

• 默认情况下，scala中的xml表达式是不可改变的，如果要修改xml元素的话，必须拷贝一份再修改

val books=<books><book>辟邪剑谱</book></books>

• 添加一个 子元素

val booksCopy=books.copy(child=books.child ++ <book>独孤九剑</book>)val book=<book id="1">book1</book>import scala.xml._//修改一个属性val bookCopy=book%Attribute(null,"id","2",Null)valbookCopy=book % Atrribute(null,"id","2",Attribute(null,"price","10.0",Null))
