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\': {
               


        

Answer 1

There is an easier way to do this now.

http://github.com/akesterson/dpath-python

$ easy_install dpath
>>> dpath.util.search(YOUR_DICTIONARY, "morefoo/morebar")

... done. Or if you don't like getting your results back in a view (merged dictionary that retains the paths), yield them instead:

$ easy_install dpath
>>> for (path, value) in dpath.util.search(YOUR_DICTIONARY, "morefoo/morebar", yielded=True)

... and done. 'value' will hold {'bacon': 'foobar'} in that case.
