Hi. Really need some help here with e4x namespace.  
Don’t really like to loop and loop in XML to get my values and there’s e4x great but a bit more complex.

This is my XML.

```auto
<?xml version='1.0' encoding='UTF-8'?>
<XMI xmlns:UML2='org.omg.xmi.namespace.UML2' xmlns:UML='org.omg.xmi.namespace.UML' xmi.version='1.5'>
    <XMI.content>
        <UML:Model xmi.id='TC_UML_758ec78c-d256-4d0f-8f7e-42384e1657bd' isSpecification='false' isRoot='false' isAbstract='false' isLeaf='false'>
            <UML:Namespace.ownedElement>
                <UML:Primitive xmi.id='TC_UML_43c15682-356c-4417-b1b3-112592101dd0' isRoot='false' isAbstract='false' isLeaf='false' isSpecification='false'>
                    <UML:ModelElement.namespace>
                        <UML:Namespace xmi.idref='TC_UML_8452543e-e086-42e9-8d09-787a9056b450'/>
                    </UML:ModelElement.namespace>
                    <UML:ModelElement.name>
                        boolean
                    </UML:ModelElement.name>

                        </UML:Class>
                    </UML:Namespace.ownedElement>
                    <UML:ModelElement.namespace>
                        <UML:Namespace xmi.idref='TC_UML_758ec78c-d256-4d0f-8f7e-42384e1657bd'/>
                    </UML:ModelElement.namespace>
                    <UML:ModelElement.name>
                        com.google.analytic
                    </UML:ModelElement.name>
                </UML:Package>
            </UML:Namespace.ownedElement>
        </UML:Model>
    </XMI.content>
</XMI>

```

What I’m looking for is to get the values easy and as you can se there’s node names with “.” and namespace.

Been trying for a while and this is what I got so far.

```auto

var ns:Namespace = new Namespace("UML","org.omg.xmi.namespace.UML");
var list : XMLList = _data.child("XMI.content")[0].ns::Model;

```

Don’t understand how to get example the next in depth “\<UML:Namespace.ownedElement\>”

You can se the complexity and problem if I start to do the old looping thing, for example when I want to compare and find id;s for  
UML:Model-\>UML:Namespace.ownedElement-\>UML: Package-\>UML:Namespace.ownedElement-\>UML:Classifier.feature-\>UML:Attribute-\>UML:Classifier-\>attribute(“xmi.idref”)

UML:Model-\>UML:Namespace.ownedElement-\>UML: Primitive-\>UML:ModelElement.namespace-\>attribute(“xmi.idref”)

Some e4x guru out there that can help 👁
