attributes | property |
attributes:Object| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
An object containing all of the attributes of the specified XMLNode instance. The
XMLNode.attributes object contains one variable for each attribute of the XMLNode instance.
Because these variables are defined as part of the object, they are generally referred to as
properties of the object. The value of each attribute is stored in the corresponding property as a
string. For example, if you have an attribute named color, you would retrieve
that attribute's value
by specifying color as the property name, as the following code shows:
var myColor:String = doc.firstChild.attributes.color

childNodes:Array [read-only] | Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
An array of the specified XMLNode object's children. Each element in the array is a reference
to an XMLNode object that represents a child node. This is a read-only property and cannot be
used to manipulate child nodes. Use the appendChild(), insertBefore(),
and removeNode() methods to manipulate child nodes.
This property is undefined for text nodes (nodeType == 3).
Implementation
public function get childNodes():ArrayRelated API Elements
firstChild | property |
public var firstChild:XMLNode| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
Evaluates the specified XMLDocument object and references the first child in the parent node's child list.
This property is null if the node does not have children. This property is
undefined if the node is a text node. This is a read-only property and cannot be used
to manipulate child nodes; use the appendChild(), insertBefore(), and
removeNode() methods to manipulate child nodes.

lastChild | property |
public var lastChild:XMLNode| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
An XMLNode value that references the last child in the node's child list. The
XMLNode.lastChild property is null if the node does not have children.
This property cannot be used to manipulate child nodes; use the appendChild(),
insertBefore(), and removeNode() methods to manipulate child nodes.
Related API Elements
localName | property |
localName:String [read-only] | Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
The local name portion of the XML node's name. This is the element name without
the namespace prefix. For example, the node
<contact:mailbox/>bob@example.com</contact:mailbox>
has the local name "mailbox", and the prefix "contact", which comprise the full
element name "contact.mailbox".
You can access the namespace prefix through the prefix property of
the XML node object. The nodeName property returns the full name
(including the prefix and the local name).
Implementation
public function get localName():StringnamespaceURI | property |
namespaceURI:String [read-only] | Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
If the XML node has a prefix, namespaceURI is the value of the xmlns
declaration for that prefix (the URI), which is typically called the namespace URI.
The xmlns declaration is in the current node or in a node higher in the XML
hierarchy.
If the XML node does not have a prefix, the value of the namespaceURI property
depends on whether there is a default namespace defined (as in
xmlns="http://www.example.com/"). If there is a default namespace, the value of
the namespaceURI property is the value of the default namespace.
If there is no default namespace, the namespaceURI property for
that node is an empty string ("").
You can use the getNamespaceForPrefix() method to identify the namespace associated with a
specific prefix. The namespaceURI property returns the prefix associated with the node name.
Implementation
public function get namespaceURI():StringRelated API Elements
nextSibling | property |
public var nextSibling:XMLNode| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
An XMLNode value that references the next sibling in the parent node's child list. This property is
null if the node does not have a next sibling node. This property cannot be used to
manipulate child nodes; use the appendChild(), insertBefore(), and
removeNode() methods to manipulate child nodes.

nodeName | property |
public var nodeName:String| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
A string representing the node name of the XMLNode object. If the XMLNode object is an XML
element (nodeType == 1), nodeName is the name of the tag that
represents the node in the XML file. For example, TITLE is the nodeName
of an HTML TITLE tag. If the XMLNode object is a text node
(nodeType == 3), nodeName is null.
Related API Elements
nodeType | property |
public var nodeType:uint| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
A nodeType constant value, either XMLNodeType.ELEMENT_NODE for an XML element or
XMLNodeType.TEXT_NODE for a text node.
The nodeType is a numeric value from the NodeType enumeration in the W3C DOM
Level 1 recommendation:
http://www.w3.org/TR/1998/REC-DOM-Level-1-19981001/level-one-core.html.
The following table lists the values:
| Integer value | Defined constant |

parentNode | property |
public var parentNode:XMLNode| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
An XMLNode value that references the parent node of the specified XML object, or returns
null if the node has no parent. This is a read-only property and cannot be used to
manipulate child nodes; use the appendChild(), insertBefore(), and
removeNode() methods to manipulate child nodes.

<contact:mailbox/>bob@example.com</contact:mailbox> prefix
"contact" and the local name "mailbox", which comprise the full element name "contact.mailbox".
The nodeName property of an XML node object returns the full name
(including the prefix and the local name). You can access the local name portion of the
element's name via the localName property.
Implementation
public function get prefix():StringpreviousSibling | property |
public var previousSibling:XMLNode| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
An XMLNode value that references the previous sibling in the parent node's child list.
The property has a value of null if the node does not have a previous sibling node. This property
cannot be used to manipulate child nodes; use the appendChild(),
insertBefore(), and removeNode() methods to manipulate child nodes.

XMLNode | () | Constructor |
public function XMLNode(type:uint, value:String)| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
Creates a new XMLNode object. You must use the constructor to create an XMLNode object before you call any of the methods of the XMLNode class.
Note: Use the createElement() and createTextNode()
methods to add elements and text nodes to an XML document tree.
type:uint — The node type: either 1 for an XML element or 3 for a text node.
| |
value:String — The XML text parsed to create the new XMLNode object.

appendChild | () | method |
public function appendChild(node:XMLNode):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
Appends the specified node to the XML object's child list. This method operates directly on the
node referenced by the childNode parameter; it does not append a copy of the
node. If the node to be appended already exists in another tree structure, appending the node to the
new location will remove it from its current location. If the childNode
parameter refers to a node that already exists in another XML tree structure, the appended child node
is placed in the new tree structure after it is removed from its existing parent node.
Parameters
node:XMLNode — An XMLNode that represents the node to be moved from its current location to the child
list of the my_xml object.

cloneNode | () | method |
public function cloneNode(deep:Boolean):XMLNode| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
Constructs and returns a new XML node of the same type, name, value, and attributes as the
specified XML object. If deep is set to true, all child nodes are
recursively cloned, resulting in an exact copy of the original object's document tree.
The clone of the node that is returned is no longer associated with the tree of the cloned item.
Consequently, nextSibling, parentNode, and previousSibling
all have a value of null. If the deep parameter is set to
false, or the my_xml node has no child nodes,
firstChild and lastChild are also null.
Parameters
deep:Boolean — A Boolean value; if set to true, the children of the specified XML object will be recursively cloned.
|
XMLNode — An XMLNode Object.

getNamespaceForPrefix | () | method |
public function getNamespaceForPrefix(prefix:String):String| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
Returns the namespace URI that is associated with the specified prefix for the node. To determine
the URI, getPrefixForNamespace() searches up the XML hierarchy from the node, as
necessary, and returns the namespace URI of the first xmlns declaration for the
given prefix.
If no namespace is defined for the specified prefix, the method returns null.
If you specify an empty string ("") as the prefix and there is a
default namespace defined for the node (as in xmlns="http://www.example.com/"),
the method returns that default namespace URI.
Parameters
prefix:String — The prefix for which the method returns the associated namespace.
|
String — The namespace that is associated with the specified prefix.

getPrefixForNamespace | () | method |
public function getPrefixForNamespace(ns:String):String| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
Returns the prefix that is associated with the specified namespace URI for the node. To determine
the prefix, getPrefixForNamespace() searches up the XML hierarchy from the node, as
necessary, and returns the prefix of the first xmlns declaration with a namespace URI
that matches ns.
If there is no xmlns
assignment for the given URI, the method returns null. If there is an
xmlns assignment for the given URI but no prefix is associated with the assignment,
the method returns an empty string
("").
Parameters
ns:String — The namespace URI for which the method returns the associated prefix.
|
String — The prefix associated with the specified namespace.

hasChildNodes | () | method |
public function hasChildNodes():Boolean| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
Indicates whether the specified XMLNode object has child nodes. This property is true if the
specified XMLNode object has child nodes; otherwise, it is false.
Boolean — Returns true if the
specified XMLNode object has child nodes; otherwise, false.

insertBefore | () | method |
public function insertBefore(node:XMLNode, before:XMLNode):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
Inserts a new child node into the XML object's child list, before the
beforeNode node. If the beforeNode parameter is undefined
or null, the node is added using the appendChild() method. If beforeNode
is not a child of my_xml, the insertion fails.
Parameters
node:XMLNode — The XMLNode object to be inserted.
| |
before:XMLNode — The XMLNode object before the insertion point for the childNode.

removeNode | () | method |
public function removeNode():void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
Removes the specified XML object from its parent. Also deletes all descendants of the node.
toString | () | method |
public function toString():String| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
Evaluates the specified XMLNode object, constructs a textual representation of the XML structure, including the node, children, and attributes, and returns the result as a string.
For top-level XMLDocument objects (those created with the constructor),
the XMLDocument.toString() method outputs the document's XML declaration
(stored in the XMLDocument.xmlDecl property), followed by the document's
DOCTYPE declaration (stored in the XMLDocument.docTypeDecl property),
followed by the text representation of all XML nodes in the object. The XML declaration is not
output if the XMLDocument.xmlDecl property is null.
The DOCTYPE declaration is not output if the
XMLDocument.docTypeDecl property is null.
String — The string representing the XMLNode object.
