    <p>I am parsing XML in PHP code and getting a warning "invalid argument supplied for foreach". Below is the XML:</p> <pre><code>&lt;?xml version="1.0" encoding="ISO-8859-1"?&gt; &lt;BookStore&gt; &lt;book&gt; &lt;title&gt;Computer Concepts&lt;/title&gt; &lt;auther&gt;Goerge Arthar&lt;/auther&gt; &lt;category&gt;Computer Science&lt;/category&gt; &lt;price&gt;24.00&lt;/price&gt; &lt;/book&gt; &lt;book&gt; &lt;title&gt;Algebra&lt;/title&gt; &lt;auther&gt;Mike&lt;/auther&gt; &lt;category&gt;Mathematics&lt;/category&gt; &lt;price&gt;34.00&lt;/price&gt; &lt;/book&gt; &lt;/BookStore&gt; </code></pre> <p>and using the following code:</p> <pre><code>&lt;?php $xmlDOM = new DOMDocument(); $xmlDOM-&gt;load("Books.xml"); $document = $xmlDOM-&gt;documentElement; foreach ($document-&gt;childNodes as $node) { foreach($node-&gt;childNodes as $temp) { echo $temp-&gt;nodeName."=".$temp-&gt;nodeValue."&lt;br /&gt;"; } } ?&gt; </code></pre> <p>NOTE: I get the output that I require but with a warning. It shows that array is not empty. Please see output also:</p> <pre><code>Warning: Invalid argument supplied for foreach() in D:\program Files\wamp\www\Test web\Day2\xmlparsing.php on line 8 #text= title=Computer Concepts #text= auther=Goerge Arthar #text= category=Computer Science #text= price=24.00 #text= Warning: Invalid argument supplied for foreach() in D:\program Files\wamp\www\Test web\Day2\xmlparsing.php on line 8 #text= title=Algebra #text= auther=Mike #text= category=Mathematics #text= price=34.00 #text= Warning: Invalid argument supplied for foreach() in D:\program Files\wamp\www\Test web\Day2\xmlparsing.php on line 8 </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.
