我正在使用 Jdom 2.0.5 并打开一个文档 one.xml，该文档通过 xinclude 包含另一个文件 two.xml。我打电话给建设者如下：

    SAXBuilder builder = new SAXBuilder();
    builder.setJDOMFactory(new LocatedJDOMFactory());
    builder.setFeature("http://apache.org/xml/features/xinclude", true);
    Document doc = builder.build(new File("c:\\temp\\one.xml"));
    XMLOutputter out = new XMLOutputter(Format.getPrettyFormat());
    System.out.println("salida es "+out.outputString(doc));

文件 one.xml 如下：

<?xml version="1.0" encoding="UTF-8" ?>
<eco xmlns:xi="http://www.w3.org/2001/XInclude">
    <tmp-path>/opt/eco/ecoprd/tmp</tmp-path>
    <!--
    <xi:include href="two.xml" parse="xml"/>
    -->
    <xi:include href="two.xml" parse="xml" xpointer="web-servers"/>
</eco>

而两个.xml如下：

<?xml version="1.0" encoding="UTF-8" ?>
<eco>
    <web-servers xml:id="web-servers">
        <valuations>
            <url-base>http://naboo:8080</url-base>
            <context>/Statements</context>
            <path>/services/ValuationsXMLGenerator</path>
        </valuations>
    </web-servers>
</eco>

包含没有 xpointer 的文件可以正常工作。但是如果我使用 xpointer，我会收到如下错误：

org.jdom2.input.JDOMParseException: Error on line 7 of document file:/c:/temp/one.xml: An 'include' failed, and no 'fallback' element was found.

我错过了什么？据说 xpointer="web-servers" 应该使用 xml:id="web-servers" 获取元素 web-serves，但事实并非如此。有什么建议么？

Xerces 仅支持 xpointer element() 方案

所以也许

<xi:include href="two.xml" parse="xml" xpointer="element(web-servers)"/>

或者

<xi:include href="two.xml" parse="xml" xpointer="element(/1/1)"/>

其中第一个 /1 是“eco”元素，第二个 /1 是“web-servers”元素

如果您想使用 xpointer，请尝试使用：http ://etourdot.github.io/xincproc/
