jmespath

The following JmesPath expression finds instances that have been tagged with a team: "Instances[?Tags[?Key=='team']]" Do you know how to find instances that are not tagged with a team? I have tried: "Instances[?!Tags[?Key=='team']]" -> !Tags[?Key=='team']]: event not found "Instances[?null==Tags[?Key=='team']]" -> [] <-- wrong answer "Instances[?!not_null(Tags[?Key=='team'])]" -> !not_null: event not found Many thanks in advance! Sample input: { "Instances": [ { "id": "i-911" , "Tags": [ {"Key":"owner", "Value":"Edu"} , {"Key":"team", "Value":"forensics"} ] , "many other keys": "stuff" } , {

I would like to use the AWS CLI to query the contents of a bucket and see if a particular file exists, but the bucket contains thousands of files. How can I filter the results to only show key names that match a pattern? For example: aws s3api list-objects --bucket myBucketName --query "Contents[?Key==*mySearchPattern*]" The --query argument uses JMESPath expressions. JMESPath has an internal function contains that allows you to search for a string pattern. This should give the desired results: aws s3api list-objects --bucket myBucketName --query "Contents[?contains(Key, `mySearchPattern`)]"

Using JMESPath, is it possible to filter output based on the existence of multiple key/value pairs within the input? From the example JSON below, what I'd like to do is extract only the objects that contain these key/value pairs within Tags - Environment / ABC Project / Project2 The closest I can get is to select a single matching Tag, but I require the rest of the object too, and I also need to match against the other key/value pair - Stacks[*].Tags[?Key=='Environment' && Value=='ABC'] Here is some exaple JSON input - { "Stacks": [ { "StackId": "abc123", "Tags": [ { "Value": "Project 1", "Key

I'm trying to filter properties of an object in jmespath based on the value of a subproperty and want to include only those properties where the subproperty is set to a specific value. Based on this example data: { "a": { "feature": { "enabled": true, } }, "b": { }, "c": { "feature": { "enabled": false } } } I'd like to get an object with all properties where the feature is enabled. { "a": { "feature": { "enabled": true, } } } I figured I could use this jmespath query to filter the objects where property. enabled is set to true. Unfortunateley, it doesn't seem to work and instead returns an

Is there a way to define a XPath type query for nested python dictionaries. Something like this: foo = { 'spam':'eggs', 'morefoo': { 'bar':'soap', 'morebar': {'bacon' : 'foobar'} } } print( foo.select("/morefoo/morebar") ) >> {'bacon' : 'foobar'} I also needed to select nested lists ;) This can be done easily with @jellybean's solution: def xpath_get(mydict, path): elem = mydict try: for x in path.strip("/").split("/"): try: x = int(x) elem = elem[x] except ValueError: elem = elem.get(x) except: pass return elem foo = { 'spam':'eggs', 'morefoo': [{ 'bar':'soap', 'morebar': { 'bacon' : { 'bla':
