XML.nodeValue 469

var myNode:XMLNode = doc.createElement("rootNode");

// place the new node into the XML tree

doc.appendChild(myNode);

// create an XML text node using createTextNode()

var myTextNode:XMLNode = doc.createTextNode("myTextNode");

// place the new node into the XML tree

myNode.appendChild(myTextNode);

trace(myNode.nodeValue);

trace(myTextNode.nodeValue);

output:

null

myTextNode

The following example creates and parses an XML packet. The code loops through each child

node, and displays the node value using the

firstChild property and firstChild.nodeValue.

When you use

firstChild to display contents of the node, it maintains the & entity.

However, when you explicitly use

nodeValue, it converts to the ampersand character (&).

var my_xml:XML = new XML("<login><username>morton</username>

<password>good&evil</password></login>");

trace("using firstChild:");

for (var i = 0; i<my_xml.firstChild.childNodes.length; i++) {

trace("\t"+my_xml.firstChild.childNodes[i].firstChild);

}

trace("");

trace("using firstChild.nodeValue:");

for (var i = 0; i<my_xml.firstChild.childNodes.length; i++) {

trace("\t"+my_xml.firstChild.childNodes[i].firstChild.nodeValue);

}

The following information writes to the log file:

using firstChild:

morton

good&evil

using firstChild.nodeValue:

morton

good&evil
