I have to try another angle on this one. I am trying to parse data from NOAA weather web service. I can parse the element conditions - icon

-<conditions-icon type="forecast-NWS" time-layout="k-p12h-n13-1">
<name>Conditions Icon</name>
<icon-link>http://forecast.weather.gov/images/wtf/medium/sct.png</icon-link> <icon-link>http://forecast.weather.gov/images/wtf/medium/nbkn.png</icon-link> <icon-link>http://forecast.weather.gov/images/wtf/medium/bkn.png</icon-link> <icon-link>http://forecast.weather.gov/images/wtf/medium/nshra50.png</icon-link> <icon-link>http://forecast.weather.gov/images/wtf/medium/shra80.png</icon-link> <icon-</conditions-icon>

I set this and then loop through the icon-link element to get the values
xmlDoc.SelectSingleNode("/dwml/data/parameters/conditions-icon[@type='forecast-NWS']")

There is another element im trying to capture but it has a different format. It doesnt have the @type value, which is the way all the other elements I need have? Im trying to get the following values from the following

-<weather time-layout="k-p12h-n13-1">
<name>Weather Type, Coverage, Intensity</name>
<weather-conditions weather-summary="Mostly Sunny"/>
<weather-conditions weather-summary="Mostly Cloudy"/>
<weather-conditions weather-summary="Mostly Cloudy"/>
<weather-conditions weather-summary="Chance Showers"/>
<weather-conditions weather-summary="Showers"/>
</weather>

I tried this but it doesnt give me anything?

xmlDoc.SelectSingleNode("/dwml/data/parameters/weather/weather-conditions")

Ive never done this so Im trying to mimic the same way I do for the conditions-icon element but it doesnt have a type, so Im not sure how to do this....

Bottom line is how do I get the values from the weather element. Im coding this in VB.NET too

I was so psyched when I got this to work but now my boss wants more and I cant figure it out.....PLEASE HELP!!!

Thanks
JK

What exactly is needed from the node?
My educated guess is that you need to query by time-layout:
xmlDoc.SelectSingleNode("/dwml/data/parameters/weather[@time-layout='k-p12h-n13-1']")

Open in new window

Note: You can get time-layout value from the previous node:
 <conditions-icon type="forecast-NWS" [b]time-layout="k-p12h-n13-1"> [/b]

Open in new window

as folllows:
Dim node As XmlNode = xmlDoc.SelectSingleNode("/dwml/data/parameters/conditions-icon[@type='forecast-NWS']");
Dim timelayout As string = node.Attributes["time-layout"].Value;

Open in new window

then use timelayout to fecth the correct weather node.
