help with geektool script for local weather xml

Ok I can get geektool to work on Yahoo weather by copying someones script see below and thanks.

Code:

curl --silent "http://xml.weather.yahoo.com/forecastrss?p=NOXX0035&u=c" | grep -E '(Current Conditions:|C<BR)' | sed -e 's/Current Conditions://' -e 's/<br \/>//' -e 's/<b>//' -e 's/<\/b>//' -e 's/<BR \/>//' -e 's/<description>//' -e 's/<\/description>//' 

However their is a local site for my location in Norway that provides great xml data for the weather. Now I can call some of the information out with grep but struggle when it gets complex. Below is an extract from the xml file

Code:

<time from="2010-08-19T00:00:00" to="2010-08-19T06:00:00" period="0">
        <!-- Valid from 2010-08-19T00:00:00 to 2010-08-19T06:00:00 -->
        <symbol number="9" name="Rain" />
        <precipitation value="0.7" />
        <!-- Valid at 2010-08-19T00:00:00 -->
        <windDirection deg="12.3" code="NNE" name="North-northeast" />
        <windSpeed mps="1.6" name="Light breeze" />
        <temperature unit="celcius" value="18" />
        <pressure unit="hPa" value="999.1" />
      </time>

This is repeated around 30 times in the xml file for different times of the day. Now I would like to get geektool to display a couple of the options on the first entry only, something like name, temp and windspeed. I keep calling too many entries.

can anyone help.

Thanks

Andy
