This is my html:

```
<div id="ref">
   <p>.....</p>
   <p>.....</p>
   abcd
</div>

```

I want to change "abcd" text to some other text say "wxyz".
How can I traverse to that text particularly in jquery?

### Edit 1:

I am asking this question in general terms, It is not necessary that it is always "abcd" or "wxyz"
