In larger JSON framework, for jsonpath analysis
it might be usefull to have more resultTypes:
* normalized path - just steps of path as an array
(w/out tracing target object)
if( P.resultType == "WAY" ) return P.normalize(expr).split(';');
P.trace(P.normalize(expr).replace(/^\$;/,""), obj, "$");
return P.result.length ? P.result : false;
* normalized traced path - with expanded expressions/filters/slices
asTrace: function(path) { return path.split(";"); }
store: function(p, v) {
if (p) P.result[P.result.length] =
( P.resultType == "PATH" ? P.asPath(p) :
( P.resultType == "TRACE" ? P.asTrace(p) : v));
return !!p;
},

Ported this to Perl, VALUE works fine, PATH option is not fully functional
though.
Additionally I've added "!" as a special character which will list all the
keys in the hash pointed to by hash indicated in the JSONPath expression.

Set a default value for vname. It is never used in the function, but without it
earlier trace functions might not work.

What steps will reproduce the problem?
1. Use a json that contain a dictionary with a key that contains a dot (for
example: {'34.3': 'value'} )
2. Try to query from the dictionary key with a dot (for example $.['34.3'])
3. Nothing will be found (but if '34.3' was '34_3', then it'd work)
What is the expected output? What do you see instead?
It should be able to query dictionary keys containing dots inside, but it isn't.
What version of the product are you using? On what operating system?
Python 2.7 with the latest version of the JsonPath library
Please provide any additional information below.
It seem that when I try to query something like "$['34.4']" it is transformed
into "$.34.4" before querying, which causes the problem

First off, many thanks for creating JsonPath - I'm having great fun with
it! However, I think I may have found an issue. When performing a JsonPath
query on a data structure containing something like
"dataResult" : {
"object" : {
"objectInfo" : {
"className" : "folder",
"typeName" : "Standard Folder",
"id" : "uniqueId"
},
then running a query like $..object.objectInfo[?(@.className=='folder')]
returns no results.
However, running the query $..object[[email protected]=='folder')] does produce
results.
It looks as though the JsonPath code is skipping the
the attached HTML file contains an example, including what I think is a
possible fix, although not being an expert, I've probably got things wrong.
Best regards,
Nick Walker

parseInt does not allow negative numbers (NumberStyles.None), this prevents
negative index selectors from working as expected. Personal fix was to use
NumberStyles.AllowLeadingSign
eg. $.data[0].values[-1:].value would return all values in path
$.data[0].values[*].value instead of expected values.

I am wondering if there is a way to extract object names from a json file. I am
working with data from archive.org and they used file names as json object
names. i.e.
http://www.archive.org/details/gd1980-09-06.aud.morris.106620.flac24&output=json
files
I have been using http://jsonpath.curiousconcept.com/ to set my queries
I can get all the file objects with $.files
I can get the value of an atribute for all the file objects with
$.files.*.format
But what I want is the file names, which are the names of the file objects.

In the PHP library the evalx() method as a $vname argument that is never
used and is causing an error when using expressions such as:
[?(@['id']>2)]

For Issue 7, the code looks explicitly for \\@ as an escaped element in the
field name. This is a great feature that should be expanded to include other
characters that need to be escaped, like dash ('-'). It is common to have
dashes in field names:
{
"first-name" : "Matt",
"last-name" : "Bishop"
}

You should avoid closures inside of the jsonPath()-function in the js-version
in order to improve performance.
Example:
(function() {
function doSomething() {};
function jsonPath() {
doSomething();
};
})();
is faster than
function jsonPath() {
function doSomething() {};
doSomething();
}
because those functions have to be created by the js-interpreter on every call
to jsonPath.

Having the test page tests/jsonpath-test-js.html show a variety of example
objects, expressions and results is really useful.
To make sense of it you need to review the output of the page (in a browser) -
which only shows the results - side-by-side with the HTML source.
The attached is an attempt to put all the useful information in the viewable
page - namely what the source data object was and the input expression. Further
to this I've included the expectations to potentially allow for regression
testing - e.g. comparison of behaviour for different jsonpath.js versions by
seeing what "fails" the expected vs actual test.
So in summary, starting with the jsonpath-test-js.html, the changes in the
attached include:
- reference to jsonpath.js is relative from /tests (../src/js/jsonpath.js)
- removed reference to json.js and using JSON.stringify(..) instead
- display (in tabular layout) the source data, expression and results
- structure of the test data changed to be (excuse the made up JSON schema):
var suite = [ <test-objects> ];
<test-object>: {
"comment": <optional test comment>,
"data": <source object>,
"tests": [ <expression-test-objects> ]
}
<expression-test-objects>: {
"expr": <jsonpath expression>,
"comment": <optional expression comment>,
"paths": [ <expected PATH result as 0-to-many paths> ],
"values": [ <expected VALUE result as 0-to-many paths> ]
}
- each expression test runs the path and value tests separately and compares
the results with the expectations. This is different to jsonpath-test-js.html
which only obtained the "PATH" result then obtained the values via 'evaluate'.
Presently, there's one test failing the "VALUE" result (Test #2, Expression
#1).
- if a comparison between expected & actual fails, the actual result is
stringified onto the page (perhaps to help update expectations)
- no-result 'false' is turned into empty array []
- added in the 'bookstore' data and example expressions and expectations from
the Wiki
I'm hoping someone else finds this useful ...
Consider for inclusion in the project? Potentially, new issues could be
captured as new "<test-object>" definitions - showing the expectation, and the
page will show if it fails.

The problem is that in the "trace" function, in the case of "[?(expr)]" the
function P.walk is applied for arrays but the simple case is not handled.
A temporal solution, that works is add a line of code to the "[?(expr)]" case:
----------Old code------------:
else if (/^\?\(.*?\)$/.test(loc)) // [?(expr)]
P.walk(loc, x, val, path, function(m,l,x,v,p) { if
(P.eval(l.replace(/^\?\((.*?)\)$/,"$1"),v[m],m)) P.trace(m+";"+x,v,p); });
----------New code------------:
else if (/^\?\(.*?\)$/.test(loc)){ // [?(expr)] Added curly brace, 2 lines
if (P.eval(loc.replace(/^\?\((.*?)\)$/,"$1"),val,null))
P.trace(x,val,path); //Added, to handle just this node
P.walk(loc, x, val, path, function(m,l,x,v,p) { if
(P.eval(l.replace(/^\?\((.*?)\)$/,"$1"),v[m],m)) P.trace(m+";"+x,v,p); });

An example object and expression filters out any book that has a price greater
than 10:
$.store.book[?(@.price < 10)].title
This expression returns 4 titles, when it should return only 2 titles.
The correct expression is:

Hi Stefan
I have now find the correct place for Jsonpath issues!
I have posted a mini demo here:
https://github.com/sailfishapps/ThrowawayDemos/blob/master/Kaputt/JsonDBDemo
This runs on Sailfish using Qt QML / Javascript
The json file has 3 entities / elements, landed, area and template. Landed is
the root, and template is a child of area.
The json file has 3 areas, each with 2 child templates.
If I apply the following query:
$.landed.area[?(@.id = 1)].template[*]
I expect to get only the templates that belong to the area with id 1. (i.e. 2
hits)
Instead I get all templates of all areas. (i.e. 6 hits)
I am running jsonpath 0.8.5
As a first step to understanding what your code is doing, I have added some
console.log calls to the trace function.
The output shows that template is being processed 3 times (once for each area).
I expect it to be processed only once due to the predicate on area.

Chris
