Matching everything between html <body> tags using PHP

I have a script that returns the following in a variable called $content

<body>
<p><span class=\"c-sc\">dgdfgdf</span></p>
</body>

I however need to place everything betwee开发者_运维百科n the body tag inside an array called matches

I do the following to match the stuff between the body tag

preg_match('/<body>(.*)<\/body>/',$content,$matches);

but the $mathces array is empty, how could I get it to return everything inside the body tag


Don't try to process html with regular expressions! Use PHP's builtin parser instead:

$dom = new DOMDocument;
$dom->loadHTML($string);
$bodies = $dom->getElementsByTagName('body');
assert($bodies->length === 1);
$body = $bodies->item(0);
for ($i = 0; $i < $body->children->length; $i++) {
    $body->remove($body->children->item($i));
}
$string = $dom->saveHTML();


You should not use regular expressions to parse HTML.

Your particular problem in this case is you need to add the DOTALL modifier so that the dot matches newlines.

preg_match('/<body>(.*)<\/body>/s', $content, $matches);

But seriously, use an HTML parser instead. There are so many ways that the above regular expression can break.


If for some reason you don't have DOMDocument installed, try this

Step 1. Download simple_html_dom

Step 2. Read the documentation about how to use its selectors

require_once("simple_html_dom.php");
$doc = new simple_html_dom();
$doc->load($someHtmlString);
$body = $doc->find("body")->innertext;
