    <p>Here's <strong>books.xml</strong>, an xml that I'm trying to traverse:</p> <pre><code>&lt;?xml version="1.0" encoding="ISO-8859-1"?&gt; &lt;!-- Edited by XMLSpy® --&gt; &lt;bookstore&gt; &lt;book category="cooking"&gt; &lt;title lang="en"&gt;Everyday Italian&lt;/title&gt; &lt;author&gt;Giada De Laurentiis&lt;/author&gt; &lt;year&gt;2005&lt;/year&gt; &lt;price&gt;30.00&lt;/price&gt; &lt;/book&gt; &lt;book category="children"&gt; &lt;title lang="en"&gt;Harry Potter&lt;/title&gt; &lt;author&gt;J K. Rowling&lt;/author&gt; &lt;year&gt;2005&lt;/year&gt; &lt;price&gt;29.99&lt;/price&gt; &lt;/book&gt; &lt;book category="web"&gt; &lt;title lang="en"&gt;XQuery Kick Start&lt;/title&gt; &lt;author&gt;James McGovern&lt;/author&gt; &lt;author&gt;Per Bothner&lt;/author&gt; &lt;author&gt;Kurt Cagle&lt;/author&gt; &lt;author&gt;James Linn&lt;/author&gt; &lt;author&gt;Vaidyanathan Nagarajan&lt;/author&gt; &lt;year&gt;2003&lt;/year&gt; &lt;price&gt;49.99&lt;/price&gt; &lt;/book&gt; &lt;book category="web" cover="paperback"&gt; &lt;title lang="en"&gt;Learning XML&lt;/title&gt; &lt;author&gt;Erik T. Ray&lt;/author&gt; &lt;year&gt;2003&lt;/year&gt; &lt;price&gt;39.95&lt;/price&gt; &lt;/book&gt; &lt;/bookstore&gt; </code></pre> <p>I want to go to each book and extract all of its children's data, however, I'm having probems: It keeps returning <strong><em>null</em></strong> instead of the values of the text nodes. Here's my code:</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;script type="text/javascript" src="loadXML.js"&gt; &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;script type="text/javascript"&gt; xmlDoc=loadXMLDoc("books.xml"); var x = xmlDoc.getElementsByTagName("book"); for(var i=0;i&lt;x.length;i++) { var y = x[i].childNodes; for(var j=0;j&lt;y.length;j++) { document.write(y[j].nodeValue); document.write("&lt;br&gt;"); } document.write("&lt;br&gt;"); } &lt;/script&gt; &lt;/body&gt; &lt;/html&gt; </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.
