I want to extract : children from "name":"recordInstanceId" from the following JSON.
The output should give me "lQBfjAu....P0tk" . How do I do it using Regex Extractor?
{
"name":"recordTypeView",
"attributes":{
"xmlns":""
},
"children":["all"
]
},{
"name":"isRuleBacked",
"attributes":{
"xmlns":""
},
"children":["false"
]
},{
"name":"recordInstanceId",
"attributes":{
"xmlns":""
},
"children":["lQBfjAu....P0tk"
]
}
If you need to extract lQBfjAu....P0tk from the following response:
{
"name": "recordInstanceId",
"attributes": {
"xmlns": ""
},
"children": [
"lQBfjAu....P0tk"
]
}
It could be done with JSON Path Extractor (available via JMeter Plugins) with a simple JSON Path Expression like:
$..children[0]
It isn't recommended to use Regular Expressions for dealing with JSON data, I would recommend extracting data from JSON responses with the JSON Path Extractor.

I have the below json
{
"swagger": "2.0",
"info": {
"version": "v2",
"title": "Portfolio"
},
"host": "portfolio.com",
"schemes": [
"https"
],
"paths": {
"/v2/clients/{clientId}/assets": {
"get": {
"tags": [
"assets"
There are multiple paths I want to extract but they all start /v2/clients so what Im looking for is everything that starts with /v2/clients but none of the sub-data that sits the below, just the full paths between the ""
I am using jmeter JSON extractor and if I use $.paths it starts at this point but brings through all the mass amount of sub-data. I've tried looking around stackoverflow but can't find exactly what I am looking for. Any help appreciated
I believe the easiest would be going for JSR223 PostProcessor and Groovy language
Add JSR223 PostProcessor as a child of the request which returns above JSON
Put the following code into "Script" area:
def index = 1
new groovy.json.JsonSlurper().parse(prev.getResponseData()).paths.each { path ->
if (path.getKey().startsWith('/v2')) {
vars.put('path_' + index, path.getKey())
index++
}
}
That's it, you will have JMeter Variables like:
path_1=/v2/clients/{clientId}/assets
path_2=/v2/foo/bar
path_3=/v2/baz/qux
etc.

Can any one help me on this ?
Assuming that the value you want to extract is the id, then add a JSON Extractor with the below configurations:
Variable names : the name of the variable which will hold the value.
JSON Path expressions : $.categories[?(#.has_products == true)].id
Match Numbers : 1 // use -1 if you want to extract all id values which pass the condition.
Default values : NOT_FOUND
Reference:
advanced-usage-json-path-extractor-jmeter but use Core JMeter JSON Extractor instead of the plugin mentioned in blog
My Response is:
{
rows{
["2","xxx","yyyy"],
["3","xxx","yyyy"],
["4","xxx","yyyy"],
}
}
I am using $.rows to get all the rows. as well I am giving $.rows[0].[1] to get the value from 1st row and 1st value..
I am trying to get the total number of rows using $.rows.size() or length. It is not following exception. How to get the number of rows?
Exception: Options AS_PATH_LIST and ALWAYS_RETURN_LIST are not allowed
when using path functions!
Given the following JSON:
{
"name":"John",
"age":30,
"cars": [
{ "name":"Ford", "models":[ "Fiesta", "Focus", "Mustang" ] },
{ "name":"BMW", "models":[ "320", "X3", "X5" ] },
{ "name":"Fiat", "models":[ "500", "Panda" ] }
]
}
If I add JSON Path Extractor as a child of the sample which returns the above JSON and configure it like:
Reference Name: arraySize
JSONPath Expression: $..cars.length()
I am able to see the following variables in the View Results Tree listener:
arraySize=[3]
arraySize_1=3
arraySize_matchNr=1
Which seems to be something you're looking for.
You can install JSON Path Extractor along with JSON Path Assertion using JMeter Plugins Manager
I want to extract JSON value based on condition using jmeter from an HTML page.
<!doctype html>
var list_data_obj = [{
"list": [
{
"field1": "123",
"field2": "xyz"
},
{
"field1": "456",
"field2": "abc"
},
{
"field1": "789",
"field2": "asdf"
}
],
"other1": "qwerty",
"other2": "asdfgh"
}]
</html>
have tried JSON Path Extractor as below but returned NULL.
$.list[?(#.field2 == 'abc')].field1
Thanks
You won't be able to use JSON Path Extractor as response data is not a valid JSON, it looks like a mix of HTML and JavaScript therefore you will need to use Regular Expression Extractor instead.
The relevant Regular Expression will look like:
"field1": "(.+?)",\s.*"field2": "abc"
References:
JMeter: Regular Expressions
Using RegEx (Regular Expression Extractor) With JMeter
Perl 5 Regex Cheat sheet
The key is to first extract a valid json using a regular expression, then apply a json path extractor on the previously extracted json.
You can perform a 2-step extraction to do this:
First Extract the Json from the page by performing a regexp extractor with "list": ([^^]+}\]), group $1$,
Then perform a Json Extractor on the extracted variable by selecting JMeter variable, then apply your json path $.list[?(#.field2 == 'abc')].field1.

How to extract data from Json with JMeter
I want to pull out href values where id : 923 using JSON extractor for Jmeter.
I tried,
$..entries[?(#.id == '923')].links[0].href
But it didn't work. How should I get the values by their id?
Here's some sample data.
"entries":[{
"id":"921",
"updated":"9999-12-31T23:59:59.999Z",
"links":[{
"href":"url1",
"rel":"related-action",
"title":"Execute related action"
},{
"href":"url2",
"rel":"icon"
}
]
},{
"id":"922",
"updated":"9999-12-31T23:59:59.999Z",
"links":[{
"href":"url3",
"rel":"related-action",
"title":"Execute action"
},{
"href":"url4",
"rel":"icon"
}
]
},{
"id":"923",
"updated":"9999-12-31T23:59:59.999Z",
"links":[{
"href":"url5",
"rel":"related-action",
"title":"Execute action"
},{
"href":"url6",
"rel":"icon"
}
]
}
]
Try removing quotation marks so your JSON Path Expression would look like:
$..entries[?(#.id == 923)].links[0].href
Your JSON is malformed, you need to surround it with {} characters in order so JSON Path Extractor could work with it.
Try updating Extras with Libs set plugin to the latest version - 1.3.0 as for the moment.
