既属性和子元素XSD元素 [英] XSD element with both attributes and child elements

问题描述

我想知道的定义含有属性和子元素（如果可能）一个元素正确的语法。例如：

I want to know the correct syntax for defining an element containing both attributes and child elements (if possible). For example:

<component type="A" binding="B">
  <operation name="X">
    <input type="C" />
  </operation>

  <event name="Y">
    <output type="D" />
  </event>
</component>

正如你所看到的，这两种元素组成，操作和事件都具有的属性和子元素。是否有可能在XSD定义呢？怎么样？

As you can see, both elements component, operation and event have both attributes and child element. Is it possible to define this in XSD? How?

非常感谢你！

推荐答案

这是一种可能的方式来定义一个XSD符合XML;学习XSD的时候，你可以报名参加该推断XSD你，从一个或多个XML文件样本启动工具的帮助。

This is one possible way to define an XSD matching your XML; when learning XSD, you could enroll the help of a tool that infers the XSD for you, starting from one or more XML sample files.

如您演练这一点，你可能会开始调整分钟/ maxOccurs的，使用（必填/可选），重用定义等生成的XSD是一个很好的起点，但通常最终被编辑过这样或那样的...

As you walkthrough this, you may start tweaking min/maxOccurs, use (required/optional), reusing definitions, etc. A generated XSD is a good starting point, but typically ends up being edited one way or another...
