jpath 1.4

Access nested dicts and lists using JSON-like path notation.

Access nested dicts and lists using JSON-like path notation.

Note that this code is written for python 3.

The notation is as follows:

You can just write the names of components in your path like you would in javascript:

foo.bar.baz

To access arrays or names with spaces in them, use the ‘[]’ notation. You can use negative indices with arrays to count from the end.

[“foo”][“bar”][“baz”] array[-1].attr [3]

You can use the wildcard character ‘*’ to iterate over all elements:

foo.*.baz [“foo”][*][“baz”]

This may return more or less than a single element. Use get to get the first one, and get_all to get a list of all possibilities. If you want to skip any number of elements in path, use two dots ‘..’:

foo..baz

You can slice the arrays just like in python:

array[1:-1:2]

Finally, you can filter the elements:

foo(bar.baz=true) foo.bar(baz>0).baz foo(bar=”yawn”).bar

At the moment only =, >, <, >=, <= and != operators are available, and you can only use them with strings, integers and boolean values.

This code was written in STX Next.
