I'm trying to write a simple JSON path query
oc get pa -o jsonpath='{range.data[*]}{#.data.vpa.pa\.poc\.hpa\\/value}{"\n"}{end}'
"data" [
{
"vpa"
{
"pa.poc.hpa/value" : 20
}
}
]
from above JSON trying to get 20
"pa.poc.hpa/value" : 20
i'm trying to pull 20 using below, but not getting value . giving empty results
pa\.poc\.hpa\\/value
I don't recognize the {} syntax you're using.
A proper JSON Path would be
$.data[*].vpa['pa.poc.hpa/value']
The [*] would search all of the items in the data array.
Because you have a non-standard property name pa.poc.hpa/value you need to use the bracket syntax with the property name in quotes.

I want to return a number and a new line
{ data : "3
"}
But every time, I try to do this it is considered invalid
Update
My parser tool tries to do things with Newlines. Here is the complete screenshot:
** Update 2**
This is with jsonlint.com
The problem is that data is not a valid key (check https://www.json.org/ or Do the JSON keys have to be surrounded by quotes?), you need to use quotes for keys in order to have valid syntax. Also you need to add \n for a new line character:
{ "data": "3\n"}
I pasted this into the console without an error:
{ "data" : "3\n"}
Testing one step further:
a = { "data" : "3\n"}
a.data + "hello" // pasted into the console
produced this:
3
hello
I'm trying to get python to create a json formatted like :
[
{
"machine_working": true
},
{
"MachineName": "TBL165-169",
"MachineType": "Rig Test"
}
]
However, i can seam to do it, this is the code i have currently but its giving me error
this_is_a_dict_too=[]
this_is_a_dict_too = dict(State="on",dict(MachineType="machinetype1",MachineName="MachineType2"))
File "c:\printjson.py", line 40
this_is_a_dict_too = dict(Statedsf="test",dict(MachineType="Rig Test",MachineName="TBL165-169")) SyntaxError: non-keyword arg after
keyword arg
this_is_a_dict_too = [dict(machine_working=True),dict(MachineType="machinetype1",MachineName="MachineType2")]
print(this_is_a_dict_too)
You are trying to make dictionary in dictionary, the error message say that you try to add element without name (corresponding key)
dict(a='b', b=dict(state='on'))
will work, but
dict(a='b', dict(state='on'))
won't.
The thing that you presented is list, so you can use
list((dict(a='b'), dict(b='a')))
Note that example above use two dictionaries packed into tuple.
or
[ dict(a='b'), dict(b='a') ]
{
"A1":{
"name":"Ad hoc",
"projectId":0
},
"X2":{
"name":"BBB",
"projectId":101
},
"AB":{
"name":"CCC",
"projectId":102
},
"recordsCount":3
}
For this JSON, how to extract values? i need output like,
A1, Ad hoc
X2, BBB
AB, CCC
experts inputs appreciated.
Analysis
XPath can't read unnamed attributes. It will always result in an exception. If you want to get the values, you need to use JsonPath.
Solution
Even then, it makes sense to add surrounding brackets, otherwise the first level will be consumed as well:
[
{
"A1":{
"name":"Ad hoc",
"projectId":0
},
"X2":{
"name":"BBB",
"projectId":101
},
"AB":{
"name":"CCC",
"projectId":102
},
"recordsCount":3
}
]
You can try the correct query on jsonpath.com. For me (with the additional brackets) the path $.* worked.
To extract the values, you need to use a tExtractJSONFields component in Talend if using a file or REST request.
A valid JSON query could be easily [0] for the field with alphanumeric identifiers.
I have an array like below. I want to parse entire data to my bash array.
So i can call the first "JSON addressLineOne" from ${bashaddr[0]}, and etc.
[
{
"id":"f0c546d5-0ce4-55ee-e043-516e0f0afdc1",
"cardType":"WMUSGESTORECARD",
"lastFour":"1682",
"cardExpiryDate":"2012-01-16",
"firstName":"robert",
"lastName":"robishaw",
"addressLineOne":"Apt venue",
"addressLineTwo":"",
"city":"oakdale",
"state":"CT",
"postalCode":"06370",
"phone":"534534",
"isDefault":false
},
{
"id":"f0c546d5-0ce0-55ee-e043-516e0f0afdc1",
"cardType":"MASTERCARD",
"lastFour":"2731",
"cardExpiryDate":"2009-08-31",
"firstName":"robert",
"lastName":"robishaw",
"addressLineOne":"119 maple ave.",
"addressLineTwo":"",
"city":"uncasville",
"state":"CT",
"postalCode":"06382",
"phone":"7676456",
"isDefault":false
},
{
"id":"f0c546d5-0ce2-55ee-e043-516e0f0afdc1",
"cardType":"MASTERCARD",
"lastFour":"6025",
"cardExpiryDate":"2011-08-31",
"firstName":"robert",
"lastName":"robishaw",
"addressLineOne":"Angeline Street",
"addressLineTwo":"",
"city":"oakdale",
"state":"CT",
"postalCode":"06370",
"phone":"7867876",
"isDefault":false
}
]
I have tried like this:
#!/bin/bash
addressLineOne="$(echo $card | jsawk 'return this.addressLineOne')"
but it gives me the entire address:
["address 1","address 2","address 3"]
Thank you.
I wrote the answer below before reading the comments, but this is exactly the same answer as #4ae1e1 provided, except I don't put -r tag in case you want the values to remain quoted (e.g. passing this as an argument somewhere else).
I know this is not jsawk, but do consider jq:
jq '.[].addressLineOne' yourfile.txt
And to access specific values you can put record number in the square brackets (starting with 0 for the first address and so on). For example to get the address for the third record:
jq '.[2].addressLineOne' yourfile.txt
For learning more about jq and advanced uses, check: http://jqplay.org
What you need to do is make use of the -a switch to apply some post processing and filter the output array like this:
jsawk 'return this.addressLineOne' -a 'return this[0]'
From the documentation:
-b <script> | -a <script>
Run the specified snippet of JavaScript before (-b) or after (-a)
processing JSON input. The `this` object is set to the whole JSON
array or object. This is used to preprocess (-b) or postprocess
(-a) the JSON array before or after the main script is applied.
This option can be specified multiple times to define multiple
before/after scripts, which will be applied in the order they
appeared on the command line.
im trying to parse a database file retrieved from a website via curl, however I having trouble trying to figure out how to get the values.
This is an example of the file
{"Databasename":[{"Var1":"Var1Value","Var2":"Var2Value","Var3":"Var3Value"},{"Var1b":"Var1bValue","Var2b":"Var2bValue","Var3b":"Var3bValue"}],"foldername":{"dbTblcountvar":"dbTblcountvalue","filecountsize":"filecountsizvalue"}}
and with line break for better readability
{
"Databasename":
[
{
"Var1":"Var1aValue",
"Var2":"Var2aValue",
"Var3":"Var3aValue"
},
{
"Var1":"Var1bValue",
"Var2":"Var2bValue",
"Var3":"Var3bValue"
},
{
"Var1":"Var1cValue",
"Var2":"Var2cValue",
"Var3":"Var3cValue"
}
],
"foldername":
{
"dbTblcountvar":"dbTblcountvalue",
"filecountsize":"filecountsizvalue"
}
}
asuming Var2 is always constant, how can i get its value? (Var2aValue,Var2bValue,Var2cValue,Var2dValue,.....)
In the example above the value im trying to get is an id for a file i need to send back to the server to download the file, and perform other operations on it.
Thanks
cat DownloadedFile.Ext | perl -pe 's/"Var2[abc]?":"(.+?)(?<![\\])"/\n\1\n/g' | grep -vPe '(?<!\\)"'
Those commands first put the Var2 (with optional a, b or c after) on a new line, then filter all lines that have a ".
I suppose that is a json file, so I avoid the matching of escaped " with this part of the regexp:
(?<!\\)
