nodeValue (XMLNode.nodeValue property)

public nodeValue : String

The node value of the XML object. If the XML object is a text node, the nodeType is 3, and the nodeValue is the text of the node. If the XML object is an XML element (nodeType is 1), nodeValue is null and read-only

Availability: ActionScript 1.0; Flash Player 5

Example

The following example creates an element node and a text node, and checks the node value of each:

// create an XML document
var doc:XML = new XML();

// create an XML node using createElement()
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("textNode");

// 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("mortongood&evil");
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 is displayed in the Output panel:

 using firstChild:
 morton
 good&amp;evil

 using firstChild.nodeValue:
 morton
 good&evil
