    <p>Before I explain the problem I'm facing, I probably need to explain the problem I wanted to solve in the first place. :)</p> <p>I have an XML that will be formatted with XSL. This XML contains HTML tags in CDATA, for example:-</p> <pre><code>&lt;doc&gt; &lt;![CDATA[ &lt;b&gt;Hello!&lt;/b&gt; ]]&gt; &lt;/doc&gt; </code></pre> <p>When XSL performs the transformation, the browser displays <code>&lt;b&gt;Hello!&lt;/b&gt;</code> rather than rendering the word <b>Hello!</b> in bold. I inspected the source code, and it looks like this:-</p> <pre><code>&lt;doc&gt; &amp;lt;b&amp;gt;Hello!&amp;lt;/b&amp;gt; &lt;/doc&gt; </code></pre> <p>To solve this problem, I'm thinking of using JQuery to render the text as HTML, like this:-</p> <pre><code>$(document).ready(function(){ var obj = $(".content"); alert("text: " + obj.text()); // to test if JQuery works obj.html(obj.text()); }); </code></pre> <p>So, I tried adding the JQuery library into XSL, and after couple of attempts and reading about the problem with <code>&lt;script&gt;</code> tag, it seems like I need to add a dummy between the opening and closing <code>&lt;script&gt;</code> tag, like this:-</p> <pre><code>&lt;script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"&gt; &lt;xsl:comment/&gt; &lt;/script&gt; </code></pre> <p>The rendered display shows 2 errors in Firebug:-</p> <pre><code>b.style is undefined (function(a,b){function ci(a){return d...a:a+"px")}}),a.jQuery=a.$=d})(window); $ is not defined </code></pre> <p>... and the javascript statements above doesn't work at all, not even the alert prompt.</p> <p>I decided to downgrade JQuery from 1.5.2 to 1.3.2 to see if that fixes anything. Now, I'm getting this error from Firebug:-</p> <pre><code>K.style is undefined (function(){var R=/((?:\((?:\([^()]+\)...,typeof K==="string"?K:K+"px")}})})(); </code></pre> <p>The good news is I'm getting the alert prompt with JQuery 1.3.2. The bad news is <code>obj.html(obj.text());</code> doesn't do anything.</p> <p>Just out of curiosity, I change <code>obj.html(obj.text());</code> to <code>obj.text("Just Testing: " + obj.text());</code>, which is a dumb test, but it works... I'm seeing <code>Just Testing:</code> being inserted into the actual content.</p> <p>How do I get <code>obj.html(obj.text());</code> to work here? Or a more general question is, how do I get the HTML tags from CData to render as HTML and not as text?</p> <p>Thanks much.</p> <p><strong>UPDATE</strong></p> <p>I did another test... <code>obj.html("aaa");</code> doesn't work either. I'm starting to believe it has something to do with the XSL transformation that prevents JQuery from working properly. I'm still using 1.3.2 here.</p>

    1. COXSL does not "render the display". It transforms an input into an output, which it sounds like you're then displaying in Firefox. If you're not outputting HTML, then Firefox won't display it as HTML. You don't need jQuery; you need to output HTML in the first place.

    2. COBefore going further please look into this: Does your server escape the characters? Because what may wind up happening is that there is so much entity-escape-un-escape going on that when you print you THINK you have unescaped entities, but you don't. Look if the <b> tags are escaped as &lt;b&gt; because injecting that into .html will cause <b> to be printed

    3. COI think the CDATA causes the `<b>` tag to show up as `&amp;lt;b&amp;gt;`... I'm seeing that in the source code, and yes, I'm using Firefox. That's the reason I want the escaped characteres to render as HTML by using `obj.html(obj.text());`, but I'm unable to get that working.

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).
