    <p>In my XML file I have some entities such as <code>&amp;rsquo;</code></p> <p>So I have created a DTD tag for my XML document to define these entities. Below is the Java code used to read the XML file.</p> <pre><code>SAXBuilder builder = new SAXBuilder(); URL url = new URL("http://127.0.0.1:8080/sample/subject.xml"); InputStream stream = url.openStream(); org.jdom.Document document = builder.build(stream); Element root = document.getRootElement(); Element name = root.getChild("name"); result = name.getText(); System.err.println(result);</code></pre> <p>How can I change the Java code to retrieve a DTD over HTTP to allow the parsing of my XML document to be error free?</p> <p>Simplified example of the xml document.</p> <pre><code> &lt;main> &lt;name>hello &amp;lsquo; world &amp;rsquo; foo &amp;amp; bar &lt;/name> &lt;/main> </code></pre>

    1. COEntities must be declared before they can be used. If you are using entity references that have not been declared(either within the file or with a reference to an external DTD), you have an invalid XML file.

    2. COIndeed. My problem is injecting the path to my DTD into the xml at runtime, as the dtd is not referenced inside the xml document. The DTD resides on a remote server which is accessible via http.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
