API with classic ASP

I'm working on a script in ASP classic to pull basic data (at first) from weatherbug but am having trouble. I'm also somewhat new to XML and using the DOMDocument, which doesn't help much.

Does anyone have any basic start-to-finish examples of grabbing say, current temp, using ASP and DOMDocument? As long as I can get started, I think I can roll with it.

Here's my basi code so far. It's just the initial code to get the data, and anything else I'm trying, like xmlDOM.getElementsByTagName("aws:weather") and then trying to get the childnodes of this isn't working. I've gotten a variety of errors, so I can't even boil it down to one problem. (wasnt sure how private the <key> is so I took it out)

Worked on it a bit more and am having some luck with:

Response.Write "Station: " & xmlDOM.getElementsByTagName("aws:station").item(0).text

Is this the correct way to pull this information? I am a bit confused as to the structure, as I intuitively thought xmlDOM.getElementsByTagName("aws:station").text would work. I am guessing now that the "aws:station" is an element and an item at the same time, but the element doesn't expose the text property?

Sorry this is mostly a DOMDocument thing, but I'm stumbling through this.

cdsloop

I know a few folks here at WeatherBug that have done this type of thing. I will get one of them to jump into the conversation and help out here.

Mark Kamensek is also a good resource. I will see if he wants to join in as well.

Msnide, it's nice to see a developer interested in our API. Here's an asp snippet that I drew up based on what has already been posted.

The code does the following:

Step 1:

Step 2:

Step3:

This is just one approach and I'm sure that our other developers could come up with alternative solutions. Be sure to change your ZipCode and enter your API code for the <key>.

Hope this gets you going again. I'm new to all this ASP stuff as well (I'm the Mac programmer here.) Let me know if you need any more examples, I'll try my best to get them to you.

Thanks Chris and cpotts....
that code makes sense on the station nodes. Two more questions:

1) how would you cycle through all the nodes in the getLiveWeather data, displaying each's name and their value with units?

When I try the following, I only get the one element:

Msnide, there is only one node per station. Currently, you can only get observations for one station at a time.

Multiple requests would be the route to go, but try to limit the number of calls you are making to 2 or 3. Anything over that will be very, very slow and inefficient.

Also, try the shorter call getLiveCompactWeather to speed things up (but you get less data.)
