Php Domdocument - Get Html Source Of Body

I'm using PHP's DOMDocument to parse and normalize user-submitted HTML using the loadHTML method to parse the content then getting a well-formed result via saveHTML: $dom= new DOMD

Solution 1:

The quick solution to your problem is to use an xPath expression to grab the body.

$dom= new DOMDocument();
$dom->loadHTML('<div><p>Hello World');      
$xpath = new DOMXPath($dom);
$body = $xpath->query('/html/body');
echo($dom->saveXml($body->item(0)));

A word of warning here. Sometimes loadHTML will throw a warning when it encounters certainly poorly formed HTML documents. If you're parsing those kind of HTML documents, you'll need to find a better html parser [self link warning].

Solution 2:

IN your case, you do not want to work with an HTML document, but with an HTML fragment -- a portion of HTML code ;; which means DOMDocument is not quite what you need.

Instead, I would rather use something like HTMLPurifier(quoting) :

HTML Purifier is a standards-compliant HTML filter library written in PHP. HTML Purifier will not only remove all malicious code (better known as XSS) with a thoroughly audited, secure yet permissive whitelist, it will also make sure your documents are standards compliant, something only achievable with a comprehensive knowledge of W3C's specifications.

And, if you try your portion of code :

<div><p>Hello World

Using the demo page of HTMLPurifier, you get this clean HTML as an output :

<div><p>Hello World</p></div>

Much better, isn't it ? ;-)

(Note that HTMLPurfier suppots a wide range of options, and that taking a look at its documentation might not hurt)

Solution 3:

Faced with the same problem, I've created a wrapper around DOMDocument called SmartDOMDocument to overcome this and some other shortcomings (such as encoding problems).

Solution 4:

This was taken from another post and worked perfectly for my use:

$layout = preg_replace('~<(?:!DOCTYPE|/?(?:html|head|body))[^>]*>\s*~i', '', $layout);
