Xpath like query for nested python dictionaries

Question

Is there a way to define a XPath type query for nested python dictionaries.

Something like this:

foo = {
  \'spam\':\'eggs\',
  \'morefoo\': {

Not exactly beautiful, but you might use sth like

def xpath_get(mydict, path):
    elem = mydict
    try:
        for x in path.strip("/").split("/"):
            elem = elem.get(x)
    except:
        pass

    return elem

This doesn't support xpath stuff like indices, of course ... not to mention the / key trap unutbu indicated.
