How can I get an element's serialised HTML with PHP's DOMDocument?

Question

This is my example script:

$html = <<
    

    Capture this text 1
    
    &l         


        

Answer 1

Well, nodeValue will give you the node's value. You want what's commonly called outerHTML

echo $dom->saveXml($tag);

will output what you are looking for in an X(HT)ML compliant way.

As of PHP 5.3.6 you can also pass a node to saveHtml, which wasnt possible previously:

echo $dom->saveHtml($tag);

The latter will obey HTML4 syntax. Thanks to Artefacto for that.
