getNamespaceForPrefix

(XMLNode.getNamespaceForPrefix method)

public getNamespaceForPrefix(prefix:String) : String

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.

Availability: ActionScript 1.0; Flash Player 8

Parameters

prefix:String - The prefix for which the method returns the associated namespace.

Returns

String - The namespace that is associated with the specified prefix.

Example

The following example creates a very simple XML object and outputs the result of a call to

getNamespaceForPrefix()

function createXML():XMLNode {

var str:String = "<Outer xmlns:exu=\"http://www.example.com/util\">"

+ "<exu:Child id='1' />"

+ "<exu:Child id='2' />"

+ "<exu:Child id='3' />"

+ "</Outer>";

return new XML(str).firstChild;

}

var xml:XMLNode = createXML();

trace(xml.getNamespaceForPrefix("exu")); // output: http://www.example.com/

util

trace(xml.getNamespaceForPrefix("")); // output: null
