What steps will reproduce the problem?
We have indefinite json path that points to more than one array:
jsonPath = "$..arr";
json:
{
obj1: {
arr: ["1", "2"]
},
obj2: {
arr: ["3", "4"]
}
}
What is the expected output? What do you see instead?
The read() method must return [["1", "2"], ["3", "4"]]
but it returns ["1", "2", "3", "4"]
What version of the product are you using? On what operating system?
version: 0.8.1
Please provide any additional information below.
The bug is in the FieldsFilter.

What steps will reproduce the problem?
1. When I try to access this json {"contents": ["one","two","three"]}
by executing this expression "$.contents[?(@=='two')]"
What is the expected output? What do you see instead?
"two" should be returned, but instead an empty result is returned.
The same happens for other filters like [?(@>2)]
What version of the product are you using? On what operating system?
0.8.1
Please provide any additional information below.
This behaviour is needed to verify for example that a value is contained in an
array. When filtering a map array this works, in the json {"contents":
["reference":"one","reference":"two"]} expression
"$.contents[?(@.reference=='two')]" returns an element.

For the JSON body:
{
list: [{
name: 'My (String)'
}]
}
The path $.list[?(@.name == 'My (String)')] will return an empty list. Where as
$.list[?(@.name == 'My(String)')] will match.
Internally the path token is getting extracted as '@.name == 'My(String)'.

Version 0.5.5
The PATTERN for ListEvalFilter incorrectly tests for property names that just
contain \\w chars, which is a class that does not include dashes ('-')
Here is a test case. Given this object:
{
"store":{
"book":[
{
"category":"reference",
"author":"Nigel Rees",
"title":"Sayings of the Century",
"display-price":8.95
},
{
"category":"fiction",
"author":"Evelyn Waugh",
"title":"Sword of Honour",
"display-price":12.99
},
{
"category":"fiction",
"author":"J. R. R. Tolkien",
"title":"The Lord of the Rings",
"isbn":"0-395-19395-8",
"display-price":22.99
},
],
"bicycle":{
"color":"red",
"display-price":19.95
}
}
}
This pattern does not return any results:
$.store.book[?(@['display-price'] < 10)].title
However, it does return one result when tested against the PHP version found
here:

What steps will reproduce the problem?
1. Use this JSON:
{
"product": [ {
"version": "3.5.5",
"codename": "Seattle"
},
{
"version": "4.0",
"codename": "Montreal"
}]
}
2. Use this predicate:
$.product[?(@.version = '4.0')].codename
3. Expect to get Montreal but get empty object.
What is the expected output? What do you see instead?
[] instead of ["Montreal"]
What version of the product are you using? On what operating system?
3.5.5
Please provide any additional information below.
The problem is in PathUtil.splitPath:
public static List<String> splitPath(String jsonPath) {
LinkedList<String> fragments = new LinkedList<String>();
if (!jsonPath.startsWith("$.")) {
jsonPath = "$." + jsonPath;
}
jsonPath = jsonPath.replace("$['","$.['")
.replaceAll("\\['(\\w+)\\.(\\w+)']", "['$1~$2']")
.replace("']['","'].['" )
.replace("..", ".~~.")
.replace("[", ".[")
.replace("@.", "@")
.replace("['", "")
.replace("']", "");
String[] split = jsonPath.split("\\.");
The split picks up also what's inside the predicate '...'.

Hi,
This is not an issue, it is more like a feature request or the desire to open a
discussion i suppose :-)
So I wanted to use jsonpath for implementing filtering on my command line tool
that deals with json data. I wanted to be able to express things like:
Do something with the given json item if: a.b==3 AND a.d!="cheese" AND a.c<2.
Programmatically, the JsonAssert style assertions are a great way to do this.
In fact I've written some code that chains a set of these assertions together
and accepts items accordingly. However, the input is quite dirty!
If the values being checked happened to be list items, i.e. the json looked
like: {"a":[{"b":1}]} then as jsonpath input one can write things like:
a[?(@.b==1)]. Nice and tidy. However, assertions against non-list values seem
to be not syntactically supported.
My current "massive hack"(tm) is to accept strings like: a.b:==1 and split on
:== and then build the assertion, taking the first half as the jsonpath and the
second half as the value to test equality against.
This is obviously not a great idea, not to mention requiring to split strings,
it doesn't support complex assertions yet, and to do so would be horrible
(given the current way im doing it)
So questions! Is there already a way to express the kind of filter? If not, is
there a plan to build assertions into jsonpath syntax? If so, can i help? :-)
Cheers!

Given this JSON : {"test":null}
JsonPath.read(json, "test") returns null
JsonPath.read(json, "nonExistingProperty") returns null
JsonPath.read(json, "nonExisting.property") throws a PathNotFoundException
I expect JsonPath.read(json, "nonExistingProperty") to throw a
PathNotFoundException as well, so I can make a difference between my json null
property and properties that does not exist.

What steps will reproduce the problem?
1. Create a class with an Object field.
2. Create an instance of the class with the field set to new Double(8.95)
3. call ExpressionEvaluator.eval() with your object, "<", "10"
public class WrappedJsonValue {
Object value;
public WrappedJsonValue(Object value) {
this.value = value;
}
public Object getValue() {
return value;
}
public static void main(String[] args) {
boolean result = ExpressionEvaluator.eval(new WrappedValue(new Double(8.95)), "<", "10");
System.out.println(result);
}
}
What is the expected output? What do you see instead?
I would like it to evaluate the Double and return true. Instead, it returns
false because it can't handle a WrappedJsonValue object.
What version of the product are you using? On what operating system?
0.9.2-SNAPSHOT, windows
Please provide any additional information below.
My use case must maintain metadata associated with JSON values - offsets in the
source document. To accomplish this, I created the following:
1. a JsonProvider to wrap/unwrap values/arrays/maps as necessary
2. an extension of JSONParserString to override readArray, readObject, and
readMain to get offsets and return one of the classes described below.
3. an extension of JSONArray, adding an Offset field
4. an extension of JSONObject, adding an Offset field
5. a wrapper class with an Offset field and an Object - to be used where a
String, Boolean, or Number would otherwise be used
This covered all of my needs except evaluating expressions such as
$.store.book[?(@.price > 10)]. The ExpressionEvaluator class assumes it will
receive a String, Boolean, or Number.
I submitted a pull request with a very simplistic, but general solution.

Json Document Example:
{ "arrayOfObjectsAndArrays" : [ { "k" : ["json"] }, { "k":["path"] }, { "k" :
["is"] }, { "k" : ["cool"] } ],
"arrayOfObjects" : [{"k" : "json"}, {"k":"path"}, {"k" : "is"}, {"k" : "cool"}]
}
What steps will reproduce the problem?
1. Given the Json Document Example (above)
2. Given at least the v 0.8.1 of the json-path jayway implementation
3. When you use any of these json-paths: $.arrayOfObjects..k and $.
arrayOfObjectsAndArrays..k
4. Then the result is this for both json-paths listed above:
["json","path","is","cool"]
What is the expected output? What do you see instead?
The expected output is: ["json","path","is","cool"] and
[["json"],["path"],["is"],["cool"]] respectively.
What version of the product are you using? On what operating system?
The version is 0.8.1
Please provide any additional information below.
In 0.8.1 the cause of this issue is an addAll during traversal when an element
is a list. This addAll ends up adding the contents of the list rather than the
list themselves into the final result.

created a JsonProvider (attached) which seems to work. With the one exception
that JSONPath.read(Object jsonObject) does not use the JsonProvider to check
for Map/List types.
In previous versions I was able to work around this by passing in a list of
JSONObject's. But this no longer seems to works.
Please consider the following change, which solves my problem:

By default JAXB (in Jersy) uses $ for @XMLValue values.
This results in the following JSON: `"foo" : {"@id" : "123", "$" : "hello"}`.
I want to get the "hello" out of this JSON using JsonPath, but can't: `foo.@id`
returns `"123"`, but `foo.$` returns `{"@id" : "123", "$" : "hello"}`.

Hi,
I've made some modification to your splitPath method such that it covers more
than one degree of escaping for key values within [' '] and I've made escaping
for keys within parentheses.
Best regards,
PL
public static void main(String[] args) {
String jsonPath = "$.['test.something.allo'].[?(@attr.version.minor)].attr.GWVersion";
Pattern p = Pattern.compile("\\['(.*)'\\]");
Matcher m = p.matcher(jsonPath);
while(m.find()) {
String withinBrackets = m.group(1);
String withoutDot = withinBrackets.replace('.', '~');
jsonPath = m.replaceFirst("['" + withoutDot + "']");
}
jsonPath = jsonPath.replace("$['","$.['")
.replace("']['","'].['" )
.replace("..", ".~~.")
.replace("[", ".[")
.replace("@.", "@")
.replace("['", "")
.replace("']", "");
System.out.println(jsonPath);
p = Pattern.compile("\\(([^\\(\\)]*)\\)");
m = p.matcher(jsonPath);
while(m.find()) {
String withinBrackets = m.group(1);
String withoutDot = withinBrackets.replace('.', '~');
jsonPath = m.replaceFirst("(" + withoutDot + ")");
}
System.out.println(jsonPath);
}

What steps will reproduce the problem?
1. With a given json of
{ "store": {
"book": [
{ "category": "reference",
"author": "Nigel Rees",
"title": "Sayings of the Century",
"price": 8.95
},
{ "category": "fiction",
"author": "Evelyn Waugh",
"title": "Sword of Honour",
"price": 12.99,
"isbn": "0-553-21311-3"
}
]
}
}
2. And if you run:
Object returnValue = JsonPath.read(givenJson, "$.bicycle.color");
What is the expected output? What do you see instead?
I would expect the returned value to be null. Because a path of "$.bicycle"
would return null. Instead the returned value is "".
What version of the product are you using? On what operating system?
0.9.1 on Windows 7.
Please provide any additional information below.
When searching for a nested object if the parent object is null will return an
empty string. However, if searching for the parent object the returned value is
null. And if the parent object exists but is empty searching for the nested
object would then return null as well.

In 1.9.1, I'm trying to implement a JsonProvider for Java 8's Nashorn native
javascript objects. jdk.nashorn.internal.objects.NativeArray is used to
represent JS arrays, but it doesn't implement Iterable. I can't write a
JsonProvider that can work with NativeArray, for the sole reason that
com.jayway.jsonpath.spi.JsonProvider.createArray() returns Iterable. In all
uses of createArray(), the variable that createArray() is assigned to is
Object. There's also a method JsonProvider.toIterable() which can take care of
converting the Object to Iterable when necessary. This method signature just
doesn't seem to fit with the rest of the interface.

What version of the product are you using? On what operating system?
0.8.0 on Windows
Right now this library uses an older version of commons-lang, which should be
updated to the latest version. As in latest version they have changed package
names (lang to lang3) thus this library is not useful with latest version. So I
request to update the code accordingly and provide a jar that is compatible
with latest commons-lang version.
Currently there is one way to solve this issue, that is:
1. Get the latest source code of json-path from Github.
2. Change the import statements of commons-lang.
3. Build jar file out of it.
Still if owner could change it and provide it as general in the download
section then this will be much better.

In PathUtil.splitPath, the first statement:

Then it does an expansion from this statement:

The library is great - thanks! One question - does this library support a
JSONPath syntax for doing multiple OR'ed expressions? I figured out you could
do this for AND:
$..book[?(@.price>10)][?(@.price<20)]
but can I do OR logical expressions also? In the javascript version, you can do:
$..book[?(@.price<10 || @.price>20)]
for OR and for AND:
$..book[?(@.price>10 & @.price<20)]
Thanks

Given JSON like:
{ "foo" : [
{ "id": 1 },
{ "id": 2 },
{ "id": 3 }
] }
a JSON-path of "$.foo.id" should not match. But it does, and it produces
[1,2,3]. The correct syntax for that result would be "$.foo[*].id"
In particular this causes a problem when the foo array is empty, as an array is
still returned.
We use json-path in rest-driver
(https://github.com/rest-driver/rest-driver).and it has been a great help for
us. But our users are raising bugs due to this behaviour which we can't work
around :(

What steps will reproduce the problem?
1. Run the following unit test
public void testArrayIndexFilter()
{
ArrayIndexFilter filter = new ArrayIndexFilter("[1:]");
Object obj = JsonLibrary.parseJson("[0,1,2,3]");
JsonProvider provider = JsonProviderFactory.createProvider();
Object value = filter.filter(obj, provider);
}
What is the expected output? What do you see instead?
I expect 'value' to equal "[1,2,3]", but instead a NumberFormatException is
raised. I believe the problem is with the following line in ArrayIndexFilter:
trimmedCondition = trim(trimmedCondition.replace(" ", ""), 1, 1);
Shouldn't this be
trimmedCondition = trim(trimmedCondition.replace(" ", ""), 0, 1);
The way it is currently trimmedCondition = "" and clearly this is going to
cause a NumberFormatException when passing to Integer.parseInt()

Additional Info:
-Can the Array Slice operator be implemented to adhere to the [start:end:step]
convention. Instead of just supporting [start:] and [:end], at the very least
could it please support [start:end]
-Also I believe 'end' is supposed to be absolute and not relative to the length
of the array. If you want to do something relative to the end of the array I
would suggest using negative values much like many other scripting languages
(ie Python)
Python Example:
>>> array=[0,1,2,3]
>>> array[0:]
[0, 1, 2, 3]
>>> array[-1:]
[3]
>>> array[:-1]
[0, 1, 2]
>>> array[0:3:2]
[0, 2]
>>> array[1:3:2]
[1]
>>> array[1:4:2]
[1, 3]
>>> array[0:4]
[0, 1, 2, 3]
May I propose the following public Object filter(Object, JsonProvider)
implementation that behaves the same as Python array slicing:
public Object filter(Object obj,JsonProvider jsonProvider, String condition) {
List<Object> src = jsonProvider.toList(obj);
List<Object> result = jsonProvider.createList();
// remove '[' and ']'
String trimmedCondition = trim(condition, 1, 1);
// resolve '@.length'
trimmedCondition.replaceAll("@.length", new Integer(src.size()).toString());
if(trimmedCondition.contains(":")){
String[] tokens = trimmedCondition.split(":");
int start = 0;
int end = src.size() - 1;
int step = 1;
try{
start = Integer.parseInt(tokens[0].trim());
if(start < 0){
start = src.size() + start;
}
}
catch(Exception ex){}
if(tokens.length > 1){
try{
end = Integer.parseInt(tokens[1].trim());
if(end < 0){
end = src.size() + end - 1;
}
else{
end -= 1;
}
}
catch(Exception ex){}
}
if(tokens.length > 2){
try{
step = Integer.parseInt(tokens[2].trim());
}
catch(Exception ex){}
}
if(step <= 0){
throw new RuntimeException("Step must be a positive value");
}
for(int i = start; i <= end; i+=step){
result.add(src.get(i));
}
return result;
}
else {
String[] indexArr = trimmedCondition.split(",");
for (String idx : indexArr) {
result.add(src.get(Integer.parseInt(idx.trim())));
}
return result;
}
}

Json blocks which are arrays must have array syntax first. If not,
ArrayIndexFilter throws NPE.
What steps will reproduce the problem?
1. Json like: [{\"a\":[{\"b\":1,\"c\":2}]}]
2. jsonpath like: $.a.b
3. calling JsonPath.read("[{\"a\":[{\"b\":1,\"c\":2}]}]", "$.a");
What is the expected output? What do you see instead?
Expected output is null because the json is an array and needs a [X] to address
an element.
Actual output:

Hi,
XPath has XPathVariableResolver which provides access to user-defined
variables. Using this, XPath substitutes a variable during evaluation.
Does JsonPath have this implemented.? Please let me know.
I don't see it being implemented in google's java implementation of JsonPath.
I am not sure where to post this to get an answer. Sorry for the trouble.
I tried at couple of places but have not got any response.
Thanks!

What steps will reproduce the problem?
1. Json like: {\"a\":{\"b\":1,\"c\":2}}
2. jsonpath like: a.d
3. calling JsonPath.read("{\"a\":{\"b\":1,\"c\":2}}", "a.d");
What is the expected output? What do you see instead?
null
What version of the product are you using? On what operating system?
invalid path exception coming from: FieldFilter.java:59:
if(!map.containsKey(condition)){
throw new InvalidPathException("invalid path");
} else {
return map.get(condition);
}
Please provide any additional information below.
version: 0.8.1
Maybe I did something wrong, but why do not I get a null value with this call?

Given some json:
{
"key": [
1, 2, 3
]
}
When I query for 'key.invalid'
Then I get 'null' - a valid json value
Current behavior is to return 'null' in this case. Looking at Issue 7 it
appears this was intentional.
However, it is confusing because 'null' is a valid json value... So it looks
like the key has a field 'invalid', and the value was 'null', when actually no
such field exists.
I would expect an InvalidPathException, which is what is thrown elsewhere when
queries are made for fields that do not exist.
What version of the product are you using? On what operating system?
master (5993e05b73c6fc1a4ad92048e2fd37edea38cf01) on Java 1.6 (OSX)
Will add pull request shortly.
