The Range.cloneContents() returns a DocumentFragment copying the objects of type Node included in the Range.
Event Listeners added using DOM Events are not copied during cloning. HTML attribute events are duplicated as they are for the DOM Core cloneNode method. HTML id attributes are also cloned, which can lead to an invalid document through cloning.
Partially selected nodes include the parent tags necessary to make the document fragment valid.
Syntax
documentFragment = range.cloneContents();
Example
range = document.createRange();
range.selectNode(document.getElementsByTagName("div").item(0));
documentFragment = range.cloneContents();
document.body.appendChild(documentFragment);
