a stab at a new wrap function for xui

xui-new-wrap.js

// private method
// Wraps the HTML in a TAG, Tag is optional
// If the html starts with a Tag, it will wrap the context in that tag.
// doesn't ACTUALLY work
function wrap(xhtml, tag) {
    // new approach
    // createDocumentFragment
    var docFrag = document.createDocumentFragment(),
        dummy,
        wrapTag;

    if (tag) {
      wrapTag = document.createElement(tag);
      wrapTag.innerHTML = xhtml;
      docFrag.appendChild(wrapTag);
    } else {
      dummy = document.createElement('div'),
      dummy.innerHTML = xhtml;

      while (dummy.children.length)
         docFrag.appendChild(dummy.children[0]);
    }

    return docFrag;
}
