<fpdl:StartNode Id="Goods_Deliver_Process.START_NODE" Name="START_NODE" DisplayName="">
    <fpdl:ExtendedAttributes>
        <fpdl:ExtendedAttribute Name="FIRE_FLOW.bounds.height" Value="20"/>
        <fpdl:ExtendedAttribute Name="FIRE_FLOW.bounds.width" Value="20"/>
        <fpdl:ExtendedAttribute Name="FIRE_FLOW.bounds.x" Value="11"/>
        <fpdl:ExtendedAttribute Name="FIRE_FLOW.bounds.y" Value="117"/>
    </fpdl:ExtendedAttributes>
</fpdl:StartNode>

fpdl is the namespace of xml, how can i operate the element of the xml by using the actionscript.I try to use example.[“fpdl:ExtendedAttribute”] to visit the element, but it doesn’t work.

Thanks.

Here’s a more complete manual of AS3 XML namespaces.

var data:XML = <fpdl:StartNode Id="Goods_Deliver_Process.START_NODE" Name="START_NODE" DisplayName="" xmlns:fpdl="http://google.com">
    <fpdl:ExtendedAttributes>
        <fpdl:ExtendedAttribute Name="FIRE_FLOW.bounds.height" Value="20"/>
        <fpdl:ExtendedAttribute Name="FIRE_FLOW.bounds.width" Value="20"/>
        <fpdl:ExtendedAttribute Name="FIRE_FLOW.bounds.x" Value="11"/>
        <fpdl:ExtendedAttribute Name="FIRE_FLOW.bounds.y" Value="117"/>
    </fpdl:ExtendedAttributes>
</fpdl:StartNode>;

// define namespace if you know its URL
var ns:Namespace = new Namespace("http://google.com");      
trace(data.ns::ExtendedAttributes.length());

// get namespace from document
ns = data.namespace("fpdl");                                
trace(data.ns::ExtendedAttributes.length());

// get default namespace from document
ns = data.namespace();                                      
trace(data.ns::ExtendedAttributes.length());

// set default namespace to use
default xml namespace = ns;
trace(data.ExtendedAttributes.ExtendedAttribute.length()); // see, no ns:: stuff

Personally I find default xml namespace = ns; to be damn ugly.
