问题描述
在XSD,SOAP和其他XML约定中,您经常会看到类似以下内容:
In XSD, SOAP and other XML conventions you'll often see things like:
<book>
<title>Harry Potter</title>
<author>J.K. Rowling</author>
</book>
现在我想知道,属性发生了什么?对我来说,将其写为:
Now I'm wondering, what happened to attributes? To me it makes more sense to write this as:
<book title="Harry Potter" author="J.K. Rowling" />
但是显然,出于某种原因,比我聪明的人选择了其他方式. 有人可以解释为什么,以及为什么要使用什么属性?
But apparently, for some reason, smarter people than me chose otherwise. Could someone explain why, and what attributes are for then?
