This is very similar to what I use in my little utility module WDM
(Web Data Mining) [1]. It helps to save a lot of (IMHO unnecessary)

I use the following "encoding":
* node[1] - node[#node] - children of the node
* node[attr] - the node attribute (like or link.href)
* node.tag - the HTML tag, because 'tag' is not used as an attribute
in (X)HTML, could be modified to 'xml' in case of XML files
