Working with XML
Use the appendChild() method to assign a new child node to the XML, as the following snippet shows:
var newItem:XML =
medium cola
1.25
myXML.appendChild(newItem);
Use the @ and . operators not only to read data, but also to assign data, as in the following:
myXML.item[0].menuName="regular burger";
myXML.item[1].menuName="small fries";
myXML.item[2].menuName="medium cola";
myXML.item.(menuName=="regular burger").@quantity = "2";
myXML.item.(menuName=="small fries").@quantity = "2";
myXML.item.(menuName=="medium cola").@quantity = "2";
Use a for loop to iterate through nodes of the XML, as follows:
var total:Number = 0;
for each (var property:XML in myXML.item)
{
var q:int = Number(property.@quantity);
var p:Number = Number(property.price);
var itemTotal:Number = q * p;
total += itemTotal;
trace(q + " " + property.menuName + " $" + itemTotal.toFixed(2))
}
trace("Total: $", total.toFixed(2));
XML objects
Flash Player 9 and later, Adobe AIR 1.0 and later
An XML object may represent an XML element, attribute, comment, processing instruction, or text element.
An XML object is classified as having either simple content or complex content. An XML object that has child nodes is
classified as having complex content. An XML object is said to have simple content if it is any one of the following: an
attribute, a comment, a processing instruction, or a text node.
For example, the following XML object contains complex content, including a comment and a processing instruction:
