My PHP script can fetch content from a div id, but what is the way to filter this fetch data and exclude some of its content which has this div id <div id="navbar" class="n"> I have tried with this code but its not working

$regex = '#\<div id="navbar"\>(.+?)\<\/div\>#s';
preg_match($regex, $displaybody, $matches);
$match = $matches[0];
echo "$match";`

To fetch content i am using HTML DOM Parser.

    Using regexpes to parse html is usually a bad idea. You can select nodes with the DOM just fine:

    $input = '<html> <body> some content <span class="a">b</span> <div id="navbar" class="n">find me <span class="a">b</span></div> </html>';

$doc = new DOMDocument;
$doc->loadHTML($input);
$navbar = $doc->getElementById('navbar');

$innerhtml = '';
foreach ($navbar->childNodes as $cn) {
    $innerhtml .= $doc->saveHTML($cn);
}
print $innerhtml;
