Select parent node

Hi there!

I've got this, (probably simple) question selecting only one specific node. 
Consider the following XML structure, how can I 
retrieve the values of the node where icon_nr = 2. I want to retrieve the 
icon's ID and the icon_title.

<icon id="2343">
        <icon_nr>1</icon_nr>
        <icon_title>Yesterday</icon_title>
</icon>
<icon id="3432">
        <icon_nr>2</icon_nr>
        <icon_title>Today</icon_title>
</icon>
<icon id="1023">
        <icon_nr>3</icon_nr>
        <icon_title>Tomorrow</icon_title>
</icon>


Thanks a lot!
Grtz, Bart
