PHP function Function to extract parts ofget URL

Another example is to check if a link is external using getPage('e') to return just the domain name.
A coded example being:

// Wrap in a div since XML must have one overall parent
$xml = simplexml_load_string('<div>'.$blog->story.'</div>');

// Iterate over all paragraph elements
foreach ($xml->children() as $p) {
    // Get external links
    // Here we specify the href of the anchor and see if the domain of the
    // anchor is the same as the domain of the current page we are on, we
    // will progress if the anchor points to an external site
    if (isset($p->a['href']) && getPage('e', $p->a['href']) != getPage('e')) {
        // Add the target attribute
        $p->a->addAttribute('target', '_blank');
    }
}

// Echo the HTML string
echo $xml->asXML();

Edited the title and added another example of how to use the function; oh, and I edited the function!
