Using XML as a data-model

Hello,
I am using an XML as a data-model, similar to this:

Map root = new HashMap();
root.put("doc", freemarker.ext.dom.NodeModel.parse(new
File("the/path/of/the.xml")));

Then, I can recurse through the document with <#recurse doc>, where
'doc' is a key name from the Map.

The question is - how can I refer to that 'doc' variable? For example,
if I don't know its' value and want to recurse through the XML
data-model.

So, if I do something like:

root.put(stringKeyName, freemarker.ext.dom.NodeModel.parse(new
File("the/path/of/the.xml")));

I need to be able to recurse in this manner:

<#recurse stringKeyName>

Thanks,
Kirill
