I have a problem with replacing HTML elements.

For example, here is a table:

<table>
    <tr>
        <td id="idTABLE">0</td>
        <td>END</td>
    </tr>
</table>

(it can be div, span, anything)

And string in JavaScript:

var str = '<td>1</td><td>2</td>';

(It can be anything, 123 text, <span>123 element</span> 456 or <tr><td>123</td> or anything)

How can I replace element idTABLE with str?

So:

<table>
    <tr>
        <td id="idTABLE">0</td>
        <td>END</td>
    </tr>
</table>

Becomes:

<table>
    <tr>
        <td>1</td>
        <td>2</td>
        <td>END</td>
    </tr>
</table> 
<!-- str = '<td>1</td><td>2</td>'; -->

<table>
    <tr>
        123 text
        <td>END</td>
    </tr>
</table>
<!-- str = '123 text' -->

<table>
    <tr> 
        <td>123</td> 
        <td>END</td>
    </tr>
</table>
<!-- str = '<td>123</td>' -->

I tried createElement, replaceChild, cloneNode, but with no result at all.
