Yes, more or less.


or in the first there are (or will be) some deprecated parameters?
are both the codes, all browser compatible?

If browsers support one, they will likely support the other. I expect the second is faster, though you'd need a very large number of child nodes to see any difference.

If you are trying to remove the entire content of an element, consider:

tab.innerHTML = '';

or:

var tempNode = tab.cloneNode(false);
tab.parentNode.replaceChild(tempNode, tab);

which I think is fastest of all, but buggy on some older browsers.
