Moving an attribute from a node to a child node

I am trying to move an attribute from one node to child node.  This seems like 
an easy
task, but I've been having issues.

Here is a sample XML document:

<myXML>
<NodeA reason="because">
<NodeB> ..... </NodeB>
</NodeA>
</myXML>

I need to move the attribute 'reason' to NodeB.  

<myXML>
<NodeA>
<NodeB reason="because"> ..... </NodeB>
</NodeA>
</myXML>



Thank you in advance!
