我怎样才能“包括"?一个 XML 文件转换为另一个 XML 文件? [英] How can I "include" one XML file into another XML file?

问题描述

我有一个 XML 模式，如:

I have a XML schema like:

<?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>

根据此架构的有效 XML 文档将是:

A valid XML document according to this schema would be:

<?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>

问题 1:有没有办法包含"另一个文件中的 TextHeader 元素?

像这样:

文件Header.xml":

File "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>

文件CompleteDocument.xml":

File "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>

问题 2:如果可能的话，.NET XMLSerializer 是否能够解析和理解包含此类包含..."的文档?

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

推荐答案

对这两个问题都不是.您可以编写一些代码(例如 app.config 如何允许导入部分，或者 xslt 如何处理包含/导入)，但这不是内置在任何 XML 规范中，并且与现有架构不匹配.基本上，您必须自己做所有事情.

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.

如果您真的想走这条路，编写一个自定义 XmlReader 来识别特定元素(在特定 xmlns 中)并在此时静默合并 - 可能是最佳选择.

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.
