E4X Filtering XML

I'm having the hardest time trying to figure out how to extract a particular node from an XML file using E4X filtering in Flash/Actionscript.

All I know is the <truck> id and I need to get the entire <plot> parent node based on that id.

For example:

var xmlList:XMLList = xml..plot.(trucks.truck.(id==The_id_I_Want));

So, if I need the plot for the truck whose id is 26, I would get the following xml snippet:

<plot woeid="2347584" location="Missouri">
  <latitude>38.2588940</latitude>
  <longitude>-92.4365880</longitude>
  <trucks>
    <truck>
      <id>26</id>
      <title><![CDATA[Main Truck]]></title>
      <operators>
        <permanent><![CDATA[JK Smith]]></permanent>
      </operators>
    </truck>
  </trucks>
</plot>

Thanks,
marc
