Joining strings

I have two xml nodes with html content in them. I need to know how I can join those two values together in flash as one string and keeping the html layout.

for example:

 

<nodeA><![CDATA[<font color="#0000FF">Some text</font>]]></nodeA>
<nodeB><![CDATA[<font color="#000000">other half of text</font>]]></nodeB>

So I load my xml get my node values for both but now I want to join them and place them in a textfiled set to html so the text from nodeA will keep its color and the text from nodeB will keep its color but they will be all in one textfield.

I presume this can be done.

Thanks
