CTreeCtrl and XML parsing

Hi,

Sorry to ask this question but I am not very good with recursion and XML
parsing.
So let's say I have a XML document defined as shown below :

<my-doc>
   <characteristic type = "A">
       <characteristic type = "B">
          <parameter name = "nameC" value="val1" />
          <parameter name = "nameD" value="val3" />
          <parameter name = "nameE" value="val8" />
       </characteristic>
   </characteristic>
</my-doc>

I would like to display this document in a CTreeCtrl like this (I am
using - to represent spaces :

- my-doc
--- characteristic: type:A
------ characteristic: type:B
--------- parameter: nameC:val1
--------- parameter: nameC:val3
--------- parameter: nameC:val8

void CXmlTreeCtrl::ParseDocument(XMLNode xmlNode)
{
   ?????
}

Since I am using xmlParser I have access to the following method (I am
showing only the one that could be interesting for my pb ):

xmlNode.getName() //return current name
int nChildNode = xmlNode.nChildNode(); // return child number
xmlNode = xmlNode.getChildNode(int i = 0); // get child node
getAttributeName(k) //self explanatory
getAttributeValue(k) //self explanatory
xmlNode.nAttribute() // return attribute number

Actually when I try to insert items since I am recursing it seems that I
  always insert items to the same root or somethig like that.
If someone could give me some tips or show me some sample code ...

Thanks
