找不到xml片段
找不到xml片段
提问于 2013-09-16 14:37:17
我试图在xml文件中包含xml片段文件，并从java代码访问parent.xml。
Java代码看起来像这样：
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位于同一位置C:/Users/admin/Desktop/，但java代码找不到child.fragment。
我得到了以下错误：
[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.

可能是程序找不到child.xml。href属性，其中包含指向要包含的文件的URL。如果使用回退，您将获得有关此问题更好信息。
<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，则会有许多限制。请查看this link。
