Example of extracting XML parsed data elements using the Assign node

<purchaseOrder>
<order>
  <item>Item 1</name>
  <price>$5.95</price>
  <description>Description of Item 1</description>
  <quantity>100</calories>
</order>
<order>
  <item>Item 2</name>
  <price>$7.95</price>
  <description>Description of Item 2</description>
  <quantity>200</calories>
</order>
</purchaseOrder>

To access XML data, create an XML list:

xmlElements = new XML(XML7500_outputData);

After creating the list, you can now extract any data from the list.

1. To get the price of Item 2, you must use a dot operator to drill down inside the XML list.

   var var1 = xmlElements.order[1].price;

   var1 output = $7.95

2. To get the price of Item 1:

   var var2 = xmlElements.order[0].price;

   var2 output = $5.95

3. To get the quantity of Item 2:

   var var3 = xmlElements.order[1].quantity;

   var3 output = 200

You can iterate through a list using a looping statement:

xmlElements = new XML(XML7500_outputData);
var getOrder = xmlElements.order;
for(var i=0; i<getOrder.length(); i++){
	var3 += xmlElements.order.item[i];
	var4 += xmlElements.order.price[i];
}

In some cases, XML data has namespace defined to it. Here is an example if an XML data has myNS namespace:

< myNS : order>
< myNS : item>Item 1</ myNS : item>
< myNS :price>$5.95</ myNS :price>
< myNS :description>Description of Item 1</ myNS :description>
< myNS :quantity>100</ myNS :quantity>
</ myNS :order>
< myNS :order>
< myNS :item>Item 2</ myNS :item>
< myNS :price>$7.95</ myNS :price>
< myNS :description>Description of Item 2</ myNS :description>
< myNS :price>200</ myNS : price>
</ myNS :food>

To access data in the XML list with namespace, you must declare the namespace in your JavaScript code.

var myNS = new Namespace(‘namespace ULR here’);

Notice that the namespace and XML element are connected by the scope resolution operator, double colon. You can iterate through an XML list with namespace using a looping statement:

xmlElements = new XML(XML7500_outputData);
var myNS = new Namespace(‘namespace ULR here’);

var getOrder = xmlElements.myNS::order;
var gfLength = Order.length();
for(var i=0; i<gfLength; i++){
	var3 += xmlElements.myNS::order.myNS::item[i];
	var4 += xmlElements.myNS::order.myNS::price[i];
}
