    <p>I'm getting some weird results while parsing some XML in JavaScript. I have the following XML in an external file:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8" ?&gt; &lt;alerts&gt; &lt;alert&gt;&lt;![CDATA[ This is the first alert message in a series... ]]&gt;&lt;/alert&gt; &lt;alert&gt;&lt;![CDATA[ This is the second alert message in a series, which features a &lt;a href="http://www.facebook.com" target="blank"&gt;hyperlink&lt;/a&gt;... ]]&gt;&lt;/alert&gt; &lt;alert&gt;&lt;![CDATA[ This is the third alert message in a series, which features &lt;span class="emphasizedAlertText"&gt;text formatted via a css rule&lt;/span&gt; ]]&gt;&lt;/alert&gt; &lt;alert&gt;&lt;![CDATA[ This is the fourth alert message in a series, which features a &lt;span class="fauxHyperlink" onclick="someFunction();"&gt;javascript call&lt;/span&gt;... ]]&gt;&lt;/alert&gt; &lt;/alerts&gt; </code></pre> <p>After grabbing the file via XMLHttpRequest, I have the following function to output it to the page:</p> <pre><code>function testFunc() { var xhrRsp = 'failed to initialize'; rslt = document.getElementById('rslt'); if(xhr.readyState == 4) { if(xhr.status == 200) { xhrRsp = xhr.responseXML; xhrTree = xhrRsp.documentElement.childNodes; rslt.innerHTML = xhrRsp + ' (' + xhrTree.length + ' nodes) '; for(var i = 0; i &lt; xhrTree.length; i++) { if(xhrTree[i].nodeName != '#text') { rslt.innerHTML = rslt.innerHTML + '&lt;br/&gt;' + xhrTree[i].nodeName + ' (' + xhrTree[i].nodeType + ') ' + ' = ' + xhrTree[i].childNodes[0].nodeValue; } } //rslt.innerHTML = outMsg; } } else { xhrRsp = 'Loading...'; } } </code></pre> <p>When I run the script in the browser, I get this as the result:</p> <pre><code>Click Me [object Document] (9 nodes) alert (1) = This is the first alert message in a series... alert (1) = This is the second alert message in a series, which features a hyperlink... alert (1) = This is the third alert message in a series, which features text formatted via a css rule alert (1) = This is the fourth alert message in a series, which features a javascript call... </code></pre> <p>I'm puzzled as to why the number of nodes comes back as 9, and why every other one of these comes in as #text, which I'm currently filtering out in the above script. I've been looking around and can't figure out what I'm missing.</p> <p>Thanks in advance!</p>

    2. COThe script is perfectly fine. `<alerts>` has 9 children, 4 element nodes and 5 text nodes. You are only outputting element nodes. I don't understand your problem...

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).
