我正在尝试在 xml 文件中包含 xml 片段文件并从 java 代码访问 parent.xml。

Java 代码如下所示：

DocumentBuilderFactory dfactory = DocumentBuilderFactory.newInstance();
dfactory.setNamespaceAware(true);
dfactory.setXIncludeAware(true);
dfactory.setFeature("http://apache.org/xml/features/xinclude/fixup-base-uris", false);
DocumentBuilder builder = dfactory.newDocumentBuilder();
Document doc = builder.parse(new FileInputStream("C:/Users/admin/Desktop/parent.xml"));

TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
StringWriter writer = new StringWriter();

transformer.transform(new DOMSource(doc), new StreamResult(writer));

String xmlFile;
xmlFile = writer.toString();
System.out.println(xmlFile);

parent.xml 文件如下所示：

<xi:include href="child.fragment" xmlns:xi="http://www.w3.org/2001/XInclude">
</xi:include>

parent.xml和child.fragment在同一个位置C:/Users/admin/Desktop/ 但是java代码找不到child.fragment..

我收到以下错误：

[Warning] Include operation failed, reverting to fallback. Resource error reading file as XML (href='child.fragment'). Reason: C:\Users\admin\Desktop\child.fragment (The system cannot find the file specified)
[Fatal Error] An include with href 'child.fragment'failed, and no fallback element was found.
Exception in thread "main" org.xml.sax.SAXParseException; An include with href 'child.fragment'failed, and no fallback element was found.

可能是程序没有找到child.xml。href 属性包含指向要包含的文件的 URL。如果使用后备，您将获得有关此问题的更好信息。

<xi:include href="child.fragment" xmlns:xi="http://www.w3.org/2001/XInclude">
<xi:fallback>
    <para>
      <emphasis>FIXME: MISSING XINCLUDE CONTENT</emphasis>
    </para>
  </xi:fallback>
</xi:include>

如果使用 include 有许多限制。请检查此链接。
