    <p>I am trying to parse an HTML document with the doctype declared to use the transitional dtd as follows:</p> <p>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "<a href="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" rel="nofollow noreferrer">http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd</a>"&gt;</p> <p>When I do Builder.build on the document, I get the following 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 at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1305) at org.apache.xerces.impl.XMLEntityManager.setupCurrentEntity(Unknown Source) at org.apache.xerces.impl.XMLEntityManager.startEntity(Unknown Source) at org.apache.xerces.impl.XMLEntityManager.startDTDEntity(Unknown Source) at org.apache.xerces.impl.XMLDTDScannerImpl.setInputSource(Unknown Source) at org.apache.xerces.impl.XMLDocumentScannerImpl$DTDDispatcher.dispatch(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source) at org.apache.xerces.parsers.DTDConfiguration.parse(Unknown Source) at org.apache.xerces.parsers.DTDConfiguration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at nu.xom.Builder.build(Builder.java:1127) at nu.xom.Builder.build(Builder.java:1019) </code></pre> <p>If I remove the doc type declaration, it parses just fine. I can successfully download the dtd from my browser, which tells me that the url is valid. I don't want to remove the doc type declaration. Is there a way tell the builder not to download the dtd or provide it with an alternate dtd?</p>

    1. COAre you parsing html from 'the wild' or did you create/have control over the pages you're parsing?

    2. COI have control over the html I am parsing, so at the very least I can remove the doctype declaration. But I am trying to stick to good practices and retain the doctype declaration.

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.

SQuiL has stopped working due to an internal error.

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