No, sorry. You talk about tables and urls, but show me DIV tags. These DIVs are also located in the HEAD section of your document, which is incorrect... there just is no way to answer the question "how do I change the URL of a DIV tag in the HEAD of my document", because:

1. DIV elements do not go in the HEAD section, and
2. DIV elements do not have a URL attribute.

In any case, the "setAttribute()" DOM method can be used to change/set an element's attributes, or, you can refer to an element's attributes directly, using the syntax I've already shown.
