Outputting XML?

Hi,

I'm sorry.  I know there is probably and obvious and well documented answer
to this question, but I sure can't find it.

How do I take XML input, add some nodes, and write out the expanded XML?

i.e. intput,
<orderlist>
    <order><price>12.95</price></order>
    <order><price>15.95</price></order>
    <order><price>7.95</price></order>
</orderlist>

resulting in...

<orderlist>
    <order><price>12.95</price><newprice> 10.95</newprice></order>
    <order><price>15.95</price><newprice> 12.95</newprice></order>
    <order><price>7.95</price><newprice> 10.95</newprice></order>
</orderlist>

Thanks in advance.
