XSD架构中的递归 [英] Recursion in XSD Schemas

问题描述

我需要创建一个递归的XSD架构来验证XML文档的树结构。



示例XML：

I need to create a recursive XSD schema that validates a tree structure of an XML document.

Sample XML:

<?xml version="1.0" encoding="UTF-8"?>
<MooNElements>
  <MooNElement>
    <MooNParameters>
      <MooNParameter/>
      <MooNParameter/>
    </MooNParameters>
    <MooNElement>
      <MooNParameters>
        <MooNParameter/>
        <MooNParameter/>
      </MooNParameters>
    </MooNElement>
    <MooNElement>
      <MooNParameters>
        <MooNParameter/>
        <MooNParameter/>
      </MooNParameters>
    </MooNElement>
  </MooNElement>
  <MooNElement>
    <MooNParameters>
      <MooNParameter/>
      <MooNParameter/>
      <MooNParameter/>
    </MooNParameters>
    <MooNElement>
      <MooNParameters>
        <MooNParameter/>
        <MooNParameter/>
      </MooNParameters>
    </MooNElement>
  </MooNElement>
  <MooNElement>
    <MooNParameters>
      <MooNParameter/>
      <MooNParameter/>
      <MooNParameter/>
    </MooNParameters>
  </MooNElement>
  <MooNElement>
    <MooNElement>
      <MooNParameters>
        <MooNParameter/>
        <MooNParameter/>
      </MooNParameters>
      <MooNElement>
        <MooNParameters>
          <MooNParameter/>
        </MooNParameters>
        <MooNElement>
          <MooNParameters>
            <MooNParameter/>
          </MooNParameters>
        </MooNElement>
      </MooNElement>
    </MooNElement>
  </MooNElement>
</MooNElements>

我使用VS 2010创建了以下XSD



XSD：

I had created the following XSD using VS 2010

XSD:

<?xml version="1.0" encoding="utf-8"?>

</xs:schema>

如何简化这个以验证递归节点？



谢谢，

How to simplify this inorder to validate the recursive nodes?

推荐答案

我建​​议使用 xsd.exe [ ^ ]，当你想从xml文件创建xsd时很有用。



如需了解更多信息，请参阅：

如何：使用XML模式定义工具生成类和XML模式文档 [ ^ ]

使用xsd.exe为XML序列化和De生成实体类-Serialization [ ^ ]

从XML到XSD [ ^ ]

I'd suggest to use xsd.exe[^], which is helpful when you want to create xsd from xml file.

For further information, please see:
