Xinclude

[Lars Vogel]

Hello,

I have written a small java program which does an XInclude via the xerces
parser which is part of Java 6.0 (
com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl).

The output includes the following signs at each line end: 

Is there a way to prevent this; this is creating additional lines into my
output?

Detailled example below.

Best regards, Lars

package test;

        Document document = null;
        File file;
        com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpltest;
        file = new File(in);
        file.getAbsolutePath();
        file.lastModified();

        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        System.out.println(dbf.getClass().toString());

        Transformer transformer = TransformerFactory.newInstance()
                .newTransformer();
        // TODO: This should be read from the input file and not hardcoded
        // here
        transformer.setOutputProperty(OutputKeys.DOCTYPE_PUBLIC,
                "-//OASIS//DTD DocBook XML V4.5//EN");
        transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,
                "../../docbook-xml-4.5/docbookx.dtd");

        DOMSource source = new DOMSource(document);
        FileOutputStream os = new FileOutputStream(new File(out));
        StreamResult result = new StreamResult(os);
        transformer.transform(source, result);
    }

    public static void main(String[] args) {
        MyXIncluder test = new MyXIncluder();
        try {
            test.extractXMLFile("article.xml",
                    "articleout.xml");
        } catch (Exception e) {
            e.printStackTrace();
            System.out.println(e.getMessage());
        }
        System.out.println("Done");
    }
}

Example article.xml:
<?xml version="1.0"?>

<article>
    <articleinfo>
        <title>
            Blabla
        </title>

        <abstract id="abstract">
            <title>Abstract</title>
            <para>
            Blablabla
            </para>
        </abstract>
    </articleinfo>

    <para>
        <programlisting>
            <xi:include xmlns:xi="http://www.w3.org/2001/XInclude";
                parse="text" href="JavaScript.java" />
        </programlisting>
    </para>
</article>

And the include file:

package counter;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

    int count;
    private Database db;

    public JavaScript() {
