    <p>I have an XML document thus:</p> <p> </p> <pre><code>&lt;tab id="1"&gt; &lt;name&gt;Individual&lt;/name&gt; &lt;coverLevel&gt; &lt;level id="1"&gt; &lt;month&gt;20&lt;/month&gt; &lt;week&gt;5&lt;/week&gt; &lt;/level&gt; &lt;level id="2"&gt; &lt;month&gt;40&lt;/month&gt; &lt;week&gt;10&lt;/week&gt; &lt;/level&gt; &lt;level id="3"&gt; &lt;month&gt;80&lt;/month&gt; &lt;week&gt;20&lt;/week&gt; &lt;/level&gt; &lt;/coverLevel&gt; &lt;/tab&gt; &lt;tab id="2"&gt; &lt;name&gt;Couple&lt;/name&gt; &lt;coverLevel&gt; &lt;level id="1"&gt; &lt;month&gt;40&lt;/month&gt; &lt;week&gt;10&lt;/week&gt; &lt;/level&gt; &lt;level id="2"&gt; &lt;month&gt;80&lt;/month&gt; &lt;week&gt;20&lt;/week&gt; &lt;/level&gt; &lt;level id="3"&gt; &lt;month&gt;160&lt;/month&gt; &lt;week&gt;40&lt;/week&gt; &lt;/level&gt; &lt;/coverLevel&gt; &lt;/tab&gt; &lt;tab id="3"&gt; &lt;name&gt;Family&lt;/name&gt; &lt;coverLevel&gt; &lt;level id="1"&gt; &lt;month&gt;80&lt;/month&gt; &lt;week&gt;20&lt;/week&gt; &lt;/level&gt; &lt;level id="2"&gt; &lt;month&gt;160&lt;/month&gt; &lt;week&gt;40&lt;/week&gt; &lt;/level&gt; &lt;level id="3"&gt; &lt;month&gt;320&lt;/month&gt; &lt;week&gt;80&lt;/week&gt; &lt;/level&gt; &lt;/coverLevel&gt; &lt;/tab&gt; &lt;tab id="4"&gt; &lt;name&gt;Single parent family&lt;/name&gt; &lt;coverLevel&gt; &lt;level id="1"&gt; &lt;month&gt;40&lt;/month&gt; &lt;week&gt;10&lt;/week&gt; &lt;/level&gt; &lt;level id="2"&gt; &lt;month&gt;80&lt;/month&gt; &lt;week&gt;20&lt;/week&gt; &lt;/level&gt; &lt;level id="3"&gt; &lt;month&gt;160&lt;/month&gt; &lt;week&gt;40&lt;/week&gt; &lt;/level&gt; &lt;/coverLevel&gt; &lt;/tab&gt; </code></pre> <p></p> <p>And jQuery which calls said XML document and dynamically updates values onClick of a table column. </p> <pre><code>$(document).ready(function(){ $('table#benefit &gt; thead &gt; tr &gt; th, table#benefit &gt; thead &gt; tr &gt; th &gt; a, table#benefit &gt; tbody &gt; tr &gt; td').click(function(){ var colIndex = $(this).parent().children().index ($(this)); var tabPosition = $('ul#coverTabs &gt; li').index ($('.currentTab')); var tabPosition = tabPosition + 1 if (colIndex != 0) { $.get('/cash-plan-quote/table.xml', function(data){ $(data).find('level').each(function() { var $level = $(this); var $levelID = $level.attr('id'); if (colIndex == $levelID) { var coverLevel = '&lt;span&gt;Level ' + $levelID + ' benefits&lt;/span&gt;'; var monthCost = '&lt;h5&gt;&amp;pound;' + $level.find('month').text() + '&lt;/h5&gt;'; var weekCost = '&lt;h6&gt;&amp;pound;' + $level.find('week').text() + '&lt;/h6&gt;'; $('div.costPanel &gt; h2 &gt; span').replaceWith($(coverLevel)); $('div.costPanel &gt; div.costs &gt; h5').replaceWith($(monthCost)); $('div.costPanel &gt; div.costs &gt; h6').replaceWith($(weekCost)); }; }); }); return false; }; }); }); </code></pre> <p>What i would like to do is retrieve the data in the XML doc for the current tab:</p> <pre><code> var tabPosition = $('ul#coverTabs &gt; li').index ($('.currentTab')); var tabPosition = tabPosition + 1 </code></pre> <p>So when a user clicks on a tab the XML level values of the tab will be called. I thought i could do this by finding the position of the tab and then use that to retrieve the data for that tab in the XML doc.</p> <p>The HTML for the tabs:</p> <pre><code>&lt;ul id="coverTabs"&gt; &lt;li class="currentTab"&gt;&lt;a href="#"&gt;Individual&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Couple&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Family&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#"&gt;Single parent family&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; </code></pre> <p>And some more jQuery to set the styling of the current tab:</p> <pre><code>$(".currentTab").removeClass("currentTab"); $(this).addClass("currentTab"); </code></pre>

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.

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