Which of the following statements will display the HREF attribute on the anchor tag if the SimpleXML object is $sxml? | In the script given in the question, HREF is the attribute of the anchor (<a>) tag. Besides this, anchor tag is inside the <h1> tag and <body> tag. Hence, you will access the HREF tag in the following way:

<pre class="prettyprint">$sxml->body->h1->a[\'href\']</pre>

Fact What is SimpleXML?
SimpleXML is a PHP extension that allows users to easily manipulate/use XML data. Its functions let a user convert XML to an object, which can be processed with property selectors and array iterators. Consider the following XML file, which describes a small collection of books in XML format. It has a root node of store having a direct child, i.e., category, which classifies the books as fiction; category has two children() labelled book; "twilight" by Stephinie Mayer and "The Bikers" by Alex R. Stuart. 

<pre class="prettyprint"><?xml version="1.0"?> 
<store>
   <category id="fiction"> 
      <book> 
         <title>twilight</title> 
         <author>Stephinie Mayer</author> 
      </book> 
      <book> 
         <title>The Bikers</title> 
         <author>Alex R. Stuart</author> 
      </book> 
   </category> 
</store>
</pre>

To extract the book title and author, a user will run the following PHP script:

<pre class="prettyprint"><?php 
   $store = simplexml_load_file(\'store.xml\');
      foreach ($store->category as $category) { 
      printf("Category %s\n", $category[\'id\']); 
         foreach ($category->book as $book) { 
         printf("<br>Title: %s\n", $book->title); 
         printf("<br>Author: %s\n", $book->author); 
      } 
   } 
?></pre>
';

\libxml_use_internal_errors(true);

$dom = new \DomDocument('1.0', 'utf8');
$dom->loadHtml($code, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);

$elements = $dom->getElementsByTagName('pre');

foreach($elements as $code){
    $newNode = $dom->createElement('pre');

    $newNode->setAttribute('class', 'prettyprint');
    $text = new \DOMText(htmlentities($code->nodeValue));
    $newNode->appendChild($text);

    $code->parentNode->replaceChild($newNode, $code);

}

var_dump($dom->saveHtml());
