Convert text to a dom element in jQuery

gistfile1.js

// Had an interesting problem today by trying to load a textarea's contents as dom elements.
// Here's what I did:

// get my value and convert into a dom element
var string = $('#article_body').val();
var element = $("<div>" + string + "</div>");

// from there, I can get what I need
element.find("video").attr('src');
