How to build a DOM tree ?
=========================

1. get a factory

  DOMBuilderFactory *factory
    = [DOMBuilderFactory standardDOMBuilderFactory];

2. get a builder for your resource type

  id<DOMBuilder> builder
    = [factory createDOMBuilderForMimeType:@"text/xml"];

3. parse what you have:

  id<DOMDocument> document
    = [builder buildFromSource:@"myfile.xml"];


KVC
===

You can navigate the DOM tree with standard key/value coding. The NGDOMDocument
will treat all KVC keys starting with a "/" as query path expressions.

Samples:
  document.documentElement             => root DOMElement
  document.documentElement.childNodes  => NSArray containing the root children
  document./uid                        => DOMElement or array! matching 'uid'
  document./uid.textValue              => text-value of 'uid' element

  element.@value.textValue    => text-value of 'value' attribute of element
  element./subnode.textValue  => lookup subnode (strips of the /) using QP
