[SOLVED] Error parsing an XML with xinclude and xpointer

Error parsing an XML with xinclude and xpointer

I'm using Jdom 2.0.5 and opening a document one.xml which includes another file two.xml through xinclude. I'm calling the builder as follows:

    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));

the file one.xml is as follows:

<?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>

and two.xml is as follows:

<?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>

the inclusion of the file without the xpointer works fine. But if I use xpointer, I get an error as follows:

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

What I'm missing? supposedly the xpointer="web-servers" should get the element web-serves with xml:id="web-servers", but it is not. Any suggestions?

Solution

Xerces only supports the xpointer element() Scheme

so maybe

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

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

where the first /1 is the "eco" element and the second /1 is the "web-servers" element
