convert string to domelement in php
Question
Is there any way to convert string to a DOMElement in php (not a DOMDocument) such that I can import it into a DOMDocumment? For example have the HTML string:
<div><div>Add Example</div><div>View more examples</div></div>
I would like to have it as though I used DOMDocument::createElement to create it. Then I would like to append it to a child of a DOMDocumment.

Unless you want to write your own HTML parser you will need to use a DOMDocument to create DOMElements.
class MyApp {
static function createElementFromHTML($doc,$str) {
$d = new DOMDocument();
$d->loadHTML($str);
return $doc->importNode($d->documentElement,true);
}
}
The problem with this method is shown in the following string
$str = "<div>1</div><div>2</div>";
This obviously doesn't have a single parent. Instead you should be ready to handle an array of DOMNode's
class MyApp {
static function createNodesFromHTML($doc,$str) {
$nodes = array();
$d = new DOMDocument();
$d->loadHTML("<html>{$str}</html>");
$child = $d->documentElement->firstChild;
while($child) {
$nodes[] = $doc->importNode($child,true);
$child = $child->nextSibling;
}
return $nodes;
}
}
