XSD for XML 具有命名空间和不组合命名空间元素 [英] XSD for XML with namespaced and no namespace elements combined

问题描述

我收到了这种 XML:

I receive this kind of XML:

<?xml version="1.0" encoding="utf-8"?>
<root-element xmlns="SomeSpecificNameSpace">
    <some-elements />
    <some-other-elements/>
    <some-other-other-element/>
    <element-with-empty-namespace xmlns=""/>
</root-element>

我必须检查我是否拥有这个 element-with-empty-namespace，但我不关心内容，所以我尝试了以下操作:

I must make a check that I've this element-with-empty-namespace, but that I don't care about the content, so I tried the following:

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema          targetNamespace="SomeSpecificNameSpace"
                    elementFormDefault="qualified"
                    xmlns="SomeSpecificNameSpace"
                    xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="MyRootElement">
        <xs:complexType>
            <xs:sequence>
            <!-- Others types here -->
            </xs:sequence>
        </xs:complexType>           
    </xs:element>
    <xs:element name="element-with-empty-namespace" minOccurs="0" maxOccurs="1" xmlns="">
        <xs:complexType>
            <xs:sequence>
                <xs:any minOccurs="0" maxOccurs="unbounded" />
            </xs:sequence>
            <xs:anyAttribute/>
        </xs:complexType>
    </xs:element>
</xs:schema

但它似乎不接受我的元素，说它需要一个命名空间为 SomeSpecificNameSpace 的元素.

but it seems it doesn't accept my element, saying that it is expecting an element with the namespace SomeSpecificNameSpace.

我知道这个结构有点奇怪，但是这个 element-with-empty-namespace 是我们通过 XML 提供的一个值".

I know that this structure is a little bit weird, but this element-with-empty-namespace is one "value" we provide through XML.

推荐答案

多个命名空间需要多个 XSD.

为了支持您的 XML 输入结构，

To support your XML input structure,

<?xml version="1.0" encoding="utf-8"?>
<root-element xmlns="SomeSpecificNameSpace"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="SomeSpecificNameSpace try.xsd">
  <some-elements />
  <some-other-elements/>
  <some-other-other-element/>
  <element-with-empty-namespace xmlns=""/>
</root-element>

将您的 XSD 分成两个文件，如下所示...

break your XSD into two files as follows...

在管理 SomeSpecificNameSpace 命名空间的主 XSD 文件中，使用 xs:import,

In the main XSD file, which governs the SomeSpecificNameSpace namespace, use xs:import,

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema targetNamespace="SomeSpecificNameSpace"
           elementFormDefault="qualified"
           attributeFormDefault="unqualified"
           xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:import schemaLocation="element-with-empty-namespace.xsd"/>

  <xs:element name="root-element">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="some-elements"/>
        <xs:element name="some-other-elements"/>
        <xs:element name="some-other-other-element"/>
        <xs:element ref="element-with-empty-namespace"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>

</xs:schema>

并导入第二个 XSD，

and import a second XSD,

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="element-with-empty-namespace">
    <xs:complexType>
      <xs:sequence>
        <xs:any minOccurs="0" maxOccurs="unbounded" />
      </xs:sequence>
      <xs:anyAttribute/>
    </xs:complexType>
  </xs:element>
</xs:schema>

将 element-with-empty-namespace 元素存放在无命名空间中.

that houses the element-with-empty-namespace element in no namespace.
