如何将一个XML文件“包含”到另一个XML文件中?

I have a XML schema like:

我有一个XML模式:

<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="MySchema"
    targetNamespace="http://tempuri.org/MySchema.xsd"
    elementFormDefault="qualified"
    xmlns="http://tempuri.org/MySchema.xsd"
    xmlns:mstns="http://tempuri.org/MySchema.xsd"
    xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="MyDocument">
    <xs:complexType>
      <xs:all>
        <xs:element name="TextHeader" type="xs:string" minOccurs="0" />
        <xs:element name="TextBody" type="xs:string" minOccurs="0" />
      </xs:all>
    </xs:complexType>
  </xs:element>
</xs:schema>

A valid XML document according to this schema would be:

根据这个模式，有效的XML文档应该是:

<?xml version="1.0" encoding="utf-8" ?>
<MyDocument xmlns="http://tempuri.org/MySchema.xsd">
  <TextHeader>My header which is almost always the same...</TextHeader>
  <TextBody>My text body which is always different...</TextBody>
</MyDocument>

Question 1: Is there a way to "include" the TextHeader element from another file?

问题1:是否有一种方法可以“包含”来自另一个文件的TextHeader元素?

Like so:

像这样:

File "Header.xml":

文件“Header.xml”:

<?xml version="1.0" encoding="utf-8" ?>
<MyDocument xmlns="http://tempuri.org/MySchema.xsd">
  <TextHeader>My Header which is almost always the same...</TextHeader>
</MyDocument>

File "CompleteDocument.xml":

文件“CompleteDocument.xml”:

<?xml version="1.0" encoding="utf-8" ?>
<MyDocument xmlns="http://tempuri.org/MySchema.xsd">

  include "Header.xml" ???

  <TextBody>My text body which is always different...</TextBody>
</MyDocument>

Question 2: If it's possible at all, will the .NET XMLSerializer be able to parse and understand the document containing such an "include..."?

问题2:如果可能的话，.NET XMLSerializer是否能够解析和理解包含“include…”的文档?

Thank you for help in advance!

提前感谢您的帮助!

No to both questions. You could code something (like how app.config allows sections to be imported, or how xslt handles includes/imports), but this is not inbuilt onto any XML spec and would not match the existing schema. You'd have to do everything yourself, basically.

没有对这两个问题。您可以编写一些东西(比如app.config如何允许导入部分，或者xslt如何处理包含/导入)，但是这不是嵌入到任何XML规范中，也不匹配现有的模式。基本上，你得自己动手。

If you really wanted to go this route, writing a custom XmlReader that recognised a specific element (in a specific xmlns) and silently merging at that point - would perhaps be the beat choice.

如果您真的想走这条路，那么编写一个自定义XmlReader来识别一个特定的元素(在特定的xmlns中)，然后在那个时候悄悄地合并——这可能是最佳选择。

If you can modify your schema, you might be able to use XML entities.

如果您可以修改您的模式，您可能可以使用XML实体。

The answer to the first question is Yes. You can do an xInclude to get the content included in the master file (http://www.w3.org/TR/xinclude/)

第一个问题的答案是肯定的。您可以使用xInclude来获取主文件中包含的内容(http://www.w3.org/TR/xinclude/)
