无法理解架构验证错误

问题描述

我正在使用带有setting.ValidationType的2.0 XmlReaderSettings对象设置

到ValdationType.Schema来根据模式验证文档。


关注是一个模式片段（名称已更改）：

< xsd：element name =" Stuff">

< xsd：complexType>

< xsd：sequence>

< xsd：element ref =" RequiredSimpleThing1" />

< xsd：element ref =" RequiredSimpleThing2" / >

< xsd：element name =" OptionalSimpleThing1" type =" OptionalType"

minOccurs =" 0" />

< xsd：element name =" OptionalSimpleThing2" type =" OptionalType"

minOccurs =" 0" />

< xsd：element name =" ComplexThing" minOccurs =" 0">

< xsd：complexType>

< xsd：sequence maxOccurs =" unbounded">

< xsd：element name =" ChildThing" type =" ChildType" />

< / xsd：sequence>

< / xsd：complexType>

< / xsd：element>

< / xsd：sequence>

< / xsd：complexType>

< / xsd：element>


以下是一个文件片段：

< Stuff>

< RequiredSimpleThing1> 86876< / RequiredSimpleThing1>

< RequiredSimpleThing2> MC< / RequiredSimpleThing2>

< ComplexThing>

<！ - 几个ChildThing元素 - >

< / ComplexThing>

< / Stuff>


我从验证器收到的错误是元素''东西''有

无效的子元素''ComplexThing''。可能元素列表

预期：''OptionalSimpleThing1，OptionalSimpleThing2''。"


为什么验证器需要这些可选（minOccurs = 0）元素？

I''m using a 2.0 XmlReaderSettings object with setting.ValidationType set
to ValdationType.Schema to validate a document against a schema.

Following is a schema fragment (names altered):
<xsd:element name="Stuff">
<xsd:complexType>
<xsd:sequence>
<xsd:element ref="RequiredSimpleThing1"/>
<xsd:element ref="RequiredSimpleThing2"/>
<xsd:element name="OptionalSimpleThing1" type="OptionalType"
minOccurs="0"/>
<xsd:element name="OptionalSimpleThing2" type="OptionalType"
minOccurs="0"/>
<xsd:element name="ComplexThing" minOccurs="0">
<xsd:complexType>
<xsd:sequence maxOccurs="unbounded">
<xsd:element name="ChildThing" type="ChildType"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>

Following is a document fragment:
<Stuff>
<RequiredSimpleThing1>86876</RequiredSimpleThing1>
<RequiredSimpleThing2>MC</RequiredSimpleThing2>
<ComplexThing>
<!-- several ChildThing elements -->
</ComplexThing>
</Stuff>

The error I recieve from the validator is "The element ''Stuff'' has
invalid child element ''ComplexThing''. List of possible elements
expected: ''OptionalSimpleThing1, OptionalSimpleThing2''."

Why is the validator requiring these optional (minOccurs = 0) elements?

推荐答案

对我来说还行。也许你的帖子过于简单了。

发布一些真正的文件（如有必要，删除并更改名称），产生错误。

Looks OK to me. Perhaps you have oversimplified in your post.
Post some real files (cut down and names changed if necessary) that produce
the error.

有充分理由不使用全部。


是 - 在抽象建模中条款是正确的，但在实践中它绝不是好主意。

There are good reasons not to use "all".

Yes - in abstract modelling terms it is correct but in practice it is never
a good idea.
