    <p>It's because you're using <code>childNodes</code> and whitespaces in the DOM are considered to be text nodes by Firefox et. al but not IE</p> <p>See <a href="https://stackoverflow.com/questions/868407/hide-an-elements-next-sibling-with-javascript/868418#868418">this answer</a> for an explanation</p> <p>My suggestions </p> <p>1.Set up some wrapper functions that ignore any <a href="http://www.javascriptkit.com/domref/nodetype.shtml" rel="nofollow noreferrer"><code>nodeType</code></a> other than 1 (<code>ELEMENT_NODE</code>) to do DOM traversing. Something like</p> <pre><code>function child(elem, index) { // if index is not supplied, default is 1 // you might be more comfortable making this 0-based // in which case change i initial assignment value to 0 too index = index || 1; // get first child element node of elem elem = (elem.firstChild &amp;&amp; elem.firstChild.nodeType != 1) ? next(elem.firstChild) : elem.firstChild; // use the index to move to nth-child element node for(var i=1; i &lt; index;i++) { (function() { return elem = next(elem); })(); } return elem; } function next(elem) { do { elem = elem.nextSibling; } while (elem &amp;&amp; elem.nodeType != 1); return elem; } </code></pre> <p>and use like so - <a href="http://jsbin.com/ajafi" rel="nofollow noreferrer"><strong>Working Demo</strong></a> - (Code at the bottom of the answer for reference)</p> <pre><code>&lt;table id="myTable"&gt; &lt;thead&gt; ... &lt;/thead&gt; &lt;tbody&gt; ... &lt;/tbody&gt; &lt;/table&gt; &lt;script type="text/javascript"&gt; child(document.getElementById('myTable'), 2); // will get the tbody &lt;/script&gt; </code></pre> <p>2.Use <code>getElementbyId()</code>, <code>getElementsByTagName()</code> or <code>getElementsByName()</code> instead of relying on position in the DOM</p> <p>3.Use a JavaScript library that abstracts away browser differences (<a href="http://www.jquery.com" rel="nofollow noreferrer">jQuery</a> comes highly recommended)</p> <p><strong>The Demo Code</strong></p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"&gt; &lt;head&gt; &lt;script type="text/javascript"&gt; window.onload = function() { document.getElementById('getCellContents').onclick = getCellContents; } function child(elem, index) { index = index || 1; elem = (elem.firstChild &amp;&amp; elem.firstChild.nodeType != 1) ?

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.
