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> '; $matches = null; $content = preg_match('#<pre class="prettyprint">(.*?)</pre>#i', $code, $matches); $matches = $matches[1]; var_dump(preg_replace("#$code#", htmlentities($content), $code));
