    <p>I want to parse with XmlSlurper a HTML document which I read using HTTPBuilder. Initialy I tried to do it this way:</p> <pre><code>def response = http.get(path: "index.php", contentType: TEXT) def slurper = new XmlSlurper() def xml = slurper.parse(response) </code></pre> <p>But it produces an exception: </p> <pre><code>java.io.IOException: Server returned HTTP response code: 503 for URL: http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd </code></pre> <p>I found a workaround to provide cached DTD files. I found a simple implementation of class which should help <a href="http://blog.bensmann.com/http-503-when-parsing-xml" rel="nofollow noreferrer">here</a>:</p> <pre><code>class CachedDTD { /** * Return DTD 'systemId' as InputSource. * @param publicId * @param systemId * @return InputSource for locally cached DTD. */ def static entityResolver = [ resolveEntity: { publicId, systemId -&gt; try { String dtd = "dtd/" + systemId.split("/").last() Logger.getRootLogger().debug "DTD path: ${dtd}" new org.xml.sax.InputSource(CachedDTD.class.getResourceAsStream(dtd)) } catch (e) { //e.printStackTrace() Logger.getRootLogger().fatal "Fatal error", e null } } ] as org.xml.sax.EntityResolver } </code></pre> <p>My package tree looks as shown below:</p> <p><img src="https://i.stack.imgur.com/1gqF9.jpg" alt="alt text"></p> <p>I modified also a little code for parsing response, so it looks like this:</p> <pre><code>def response = http.get(path: "index.php", contentType: TEXT) def slurper = new XmlSlurper() slurper.setEntityResolver(org.yuri.CachedDTD.entityResolver) def xml = slurper.parse(response) </code></pre> <p>But now I'm getting <code>java.net.MalformedURLException</code>. Logged DTD path from CachedDTD entityResolver is <code>org/yuri/dtd/xhtml1-transitional.dtd</code> and I can't get it working...</p>

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.
