Here is my code: <http://jsfiddle.net/zEXrq/8/>

Also I need to check `<li>` tag and `<h3>` tags.

Is it possible to check other words into those tags like `<a onclick="word_desc(23); classChange(1, 1);" id="txtid1" class="sel25">user key</a>` - here I want to replace only "user key", but when I put "a" to replace all "a" words including `<a>` tag and other words inside tags are replaced. How to solve this?
