Note: <a href="http://msdn.microsoft.com/en-us/magazine/ee335713.aspx" rel="noreferrer">XML validation</a> could be subject to the <a href="http://en.wikipedia.org/wiki/Billion_laughs" rel="noreferrer">Billion Laughs</a> attack, and similar DoS vectors. This essentially does what rojoca mentioned in his comment: <pre><code><?php $xml = <<<END <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE foo SYSTEM "foo.dtd"> <foo> <bar>baz</bar> </foo> END; $root = 'foo'; $old = new DOMDocument; $old->loadXML($xml); $creator = new DOMImplementation; $doctype = $creator->createDocumentType($root, null, 'bar.dtd'); $new = $creator->createDocument(null, null, $doctype); $new->encoding = "utf-8"; $oldNode = $old->getElementsByTagName($root)->item(0); $newNode = $new->importNode($oldNode, true); $new->appendChild($newNode); $new->validate(); ?> </code></pre> This will validate the document against the <code>bar.dtd</code>. You can't just call <code>$new->loadXML()</code>, because that would just set the DTD to the original, and the <code>doctype</code> property of a DOMDocument object is read-only, so you have to copy the root node (with everything in it) to a new DOM document. I only just had a go with this myself, so I'm not entirely sure if this covers everything, but it definitely works for the XML in my example. Of course, the quick-and-dirty solution would be to first get the XML as a string, search and replace the original DTD by your own DTD and then load it.

Guidance

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.
