html pre tag, extract text only?

[Bni]

Is there anyway to extract text of a pre element using JavaScript?

example:
<pre>
<span style="color:red">red</span>
<span style="color:blue">blue</span>
</pre>

convert to:
redblue

user the html color code instead of give red eg

<pre>
<span style="color:#232323">red</span>
<span style="color:#232323">blue</span>
</pre>
