• If item is a QueryPath, then the first item is retrieved and this call function is called recursivel.
• If the item is a DOMNode, it is imported into the current DOM if necessary.
• If the item is a SimpleXMLElement, it is converted into a DOM node and then imported.

Parameters

mixed $item: Item to prepare for insert.

Return value

mixed Returns the prepared item.

Throws

QueryPathException Thrown if the object passed in is not of a supprted object type.
