Aaron,

I cannot answer all your questions here, but I have done this in my code 
(snippets)

 *  Get the node name                                                   
C                   EVAL      Domstrptr@ = QxmlDOM_Node_getNodeName    
C                                          (nodlstptr@)                
C                   EVAL      element = %str(                          
C                             QxmlDOMString_transcode(Domstrptr@))     
 *                                                                     
C                   CALLP     QxmlDOMString_delete(Domstrptr@)         
  * get value of element or attribute
 C                   Eval      Nodeptr@ = QxmlDOM_Node_getFirstChild

All the pointers used in my PGM are defined global.

to get a child element's value I need to call _Node_getFirstChild, 
_Node_getNodeValue, string_transcode, pointers required: Domstrptr@, Nodeptr@

to get the child element you use the _Node_getNodeName and string_transcode, 
using the same pointer.

I removed the code that retrieved values like '#text', as I do not need that.
