Archived:How to load and parse XML files

From Nokia Developer Wiki
Jump to: navigation, search

Compatibility: Flash Lite 2.x

We will be using this basic XML document:

<modelName>Nokia N73</modelName>
<type>ARM 9</type>


Loading XML files

This following script load an XML file:

// create a new XML object
var myPhoneXML = new XML();
//Text nodes that contain only white space are discarded
myPhoneXML.ignoreWhite = true;
// define the onload handler
myPhoneXML.onLoad = function(success) {
if (success) {
trace("XML loaded");
} else {
trace("Loading failed");
// load the XML file into the myPhoneXML object
  • The load() method on the XML object allows you to download data from a remote host.
  • When the data is finished downloading, the onLoad event of the XML object occurs.

XML Navigation

  • firstChild: The first child in the parent node's child list
// Output: <myPhone>[...]</myPhone>
// Output: <modelName>[...]</modelName>

  • lastChild: The last child in the parent node's child list
// Output: <cpu>[...]</cpu>

  • nextSibling: The next node in the parent node's child list
// Output: <screen>[...]</screen>

  • previousSibling: The previous node in the parent node's child list

Getting nodes value

  • This example check the <clock_rate> node value:
// Output: 220

  • Another example using user XMLNode objects to get the screen resolution
var screenNode:XMLNode = myPhoneXML.firstChild.firstChild.nextSibling;
trace("Resolution: " + screenNode.firstChild.firstChild.nodeValue + " x " +
// Output: Resolution: 240 x 320
  • Another example by iterating through the child nodes
for (var aNode:XMLNode = myPhoneXML.firstChild.firstChild.nextSibling.firstChild;aNode != null;aNode=aNode.nextSibling) {
// Output: 240
// 320
