XML Basics

Here is the basic syntax of XML; I will explain the methods and properties of XML in common use with a simple example.


Series: SWF Quicker 2.0
Estimated Time of Completion: 18 minutes 


1. Build XML object:

Code:
var myXML = new XML();

2. Load XML file:

Code:
myXML.load("data.xml");

 

3. Ignore white space in XML file:

Code:
myXML.ignoreWhite = true;//Default setting is false.

 

4. Process function of XML Object:

Code:
myXML.onLoad = function(success) {
   if (success) {
      statements;
   }
}

 

5. Contents of "data.XML" file:
<xml version="1.0" encoding="UTF-8" ?>
<data1 name="imagebear">
<data2 name="mariger">xiaoshandong</data2>
<data3 name="mariger3">xiaoshandong3</data3>
</data1>


6. Using trace to display the return value:

myXML.childNodes[0] will return:
<data1 name="imagebear">
<data2 name="mariger">
xiaoshandong
</data2>
<data3 name="mariger3">
xiaoshandong3
</data3>
</data1>


 

myXML.childNodes[0].nodeName will return:
data1

 

myXML.childNodes[0].attributes.name will return:
imagebear

 

myXML.childNodes[0].childNodes[0] will return:
<data2 name="mariger">
xiaoshandong
</data2>


 

myXML.childNodes[0].childNodes[0].nodeName will return:
data2

 

myXML.childNodes[0].childNodes[1].attributes.name will return:
mariger3

 

myXML.childNodes[0].childNodes[0].childNodes[0].nodeValue
xiaoshandong

 

Code:
var myName = myXML.firstChild.firstChild;
trace(myName.nodeName);//data2 will be exported.
myName = myName.nextSibling;
trace(myName.nodeName);//data3 will be exported, childNodes[0] is equal to firstChild.

 

7. If you test the following codes and look at the trace value, you will understand the usage.

Code:
var myXML = new XML();
myXML.load("data.xml");
myXML.ignoreWhite = true;
myXML.onLoad = function(success) {
  if(success) {
    myArray = myXML.childNodes[0];
    trace(myArray.attributes.name);
    trace(myXML.childNodes[0].childNodes[1].firstChild.nodeValue);
    trace(myXML.firstChild);
    trace(myXML.childNodes[0].nodeName);
    trace(myXML.firstChild.attributes.name);
    trace(myXML.childNodes[0].childNodes[1].nodeName);
    trace(myXML.childNodes[0].childNodes[1].attributes.name);
    trace(myXML.firstChild.firstChild);
    trace(myXML.firstChild.firstChild.nodeName);
    trace(myXML.firstChild.firstChild.attributes.name);
    trace(myXML.childNodes[0].childNodes[0].childNodes[0].nodeValue);

    var myName = myXML.firstChild.firstChild;
    trace(myName.nodeName);
    myName = myName.nextSibling;
    trace(myName.nodeName);
  }
};

 

 Hopefully it is helpful to you!
