Parsing XML - Need Help Extracting Data

Hello,

Using Classic ASP (not ASP.net) and am trying to integrate with USPS Real Time Shipping and I am having trouble parsing and extracting data from the International XML Reponse.

I have the code loaded into the XML Parser but I am just unsure of the actual code to extract exactly what I need.

The response is similar to what is below.

<IntlRateResponse>
  <Package ID="0">
    <Service ID="1">
      <Pounds>1</Pounds>
      <Ounces>14</Ounces>

Code (markup):

What I need is for SERVICE ID=1 and SERVICE ID=2 ONLY is the value for "POSTAGE".

I don't need any of the other Service Levels... but it is important the programming pick up ID=1 and ID=2 and ignore the rest.

Basically, I guess I need a way to loop through the nodes and if it comes across 1 or 2 for Service, to grab the value for "Postage" and either store each value in a separate variable or an array.

I am stuck. If someone can help, it'd be greatly appreciated.

Oh - Package ID will ALWAYS be 0 and will be the only one.

 

It took me a while but since I knew the ID's were a constant, rather than looping through the entire XML, I just extracted what I needed using the following:

xmlDoc.selectSingleNode("//IntlRateResponse/Package/Service[@ID='2']/Postage").text

Probably not the cleanest way of getting the data I needed but it works. I'll still try and find a permanent solution but for now, this accomplishes what I need.
