I am trying to parse a string with is in form of dictionary or lists of dictionaries.
And I am trying to parse it into a JSON object.
But json.loads() is giving me an error.
How do I do this?
Thanks in Advance.
A sample portion of the file is as below:
{
"Andhra Pradesh":
[
{
"code": "ANAN",
"name": "Anantapur"
},
{
"code": "CHDM",
"name": "Chinnamandem"
},
{
"code": "GUDR",
"name": "Gudur"
},
{
"code": "GUNT",
"name": "Guntur"
},
{
"code": "JANG",
"name": "Jangareddy Gudem"
}
],
"Karnataka":
[
{
"code": "BANG",
"name": "Bangalore"
},
{
"code": "HUBL",
"name": "Hubli"

},
{
"code": "JABL",
"name": "Jabalpur"
},
{
"code": "UJJN",
"name": "Ujjain"
}
]
}
json.loads()
try this one..
import json
d = json.loads(sringToConvertToArray)
print d['Andhra Pradesh']['code']
In [1]: import json
In [2]: with open(r'YourTestFile.txt','r') as fh:
....: a = json.load(fh)
....: print a["Karnataka"][1]['code']
....:
HUBL
import and use jsonify on the raw content, pack it and ship it.
repacked_json = json.dumps(raw_json_data)
json_obj = json.loads(repacked_json)
return jsonify(result = json_obj)

If I have the following code and want to convert to XML:
Note: I tried using json2xml, but it doesn't convert the complete set, rather just converts a segment of it.

Is there any Python library or dedicated code to do this?
I tried building custom functions to break this out and convert them all, but, I am rather stuck in this problem.
The use case here is the code above input and the output should be the code generated by any online converter
EDIT:
from json2xml import json2xml
from json2xml.utils import readfromurl, readfromstring, readfromjson
data = readfromstring(string)
print(json2xml.Json2xml(data).to_xml()
Above code only converts a part of the json like the below code to xml:
{
"record": {
"model": "ir.ui.view",
"id": "address_tree_view",
"field": [
{
"name": "name",
"#text": "address.tree.view"
},
{
"name": "model",
"#text": "address"
},
{
"name": "priority",
"eval": "16"
},
{
"name": "arch",
"type": "xml",
"tree": {
"string": "Address",
"field": [
{
"name": "text_address"
},
{
"name": "address_line1"
},
{
"name": "country_id"
},
{
"name": "state_id"
},
{
"name": "address_district"
},
{
"name": "address_city"
},
{
"name": "address_postal_code"
}
]
}
}
]
}
}
PS: I have used the online converters but, I don't want to do that over here.
Use dicttoxml to convert JSON directly to XML
Installation
pip install dicttoxml
or
easy_install dicttoxml
In [2]: from json import loads
In [3]: from dicttoxml import dicttoxml
In [4]: json_obj = '{"main" : {"aaa" : "10", "bbb" : [1,2,3]}}'
In [5]: xml = dicttoxml(loads(json_obj))
In [6]: print(xml)
<?xml version="1.0" encoding="UTF-8" ?><root><main type="dict"><aaa type="str">10</aaa><bbb type="list"><item type="int">1</item><item type="int">2</item><item type="int">3</item></bbb></main></root>
In [7]: xml = dicttoxml(loads(json_obj), attr_type=False)
In [8]: print(xml)
<?xml version="1.0" encoding="UTF-8" ?><root><main><aaa>10</aaa><bbb><item>1</item><item>2</item><item>3</item></bbb></main></root>
For more information check here
trydicttoxml libary
if you are retrieving data from a JSON file
import json
import dicttoxml
with open("file_name.json", "r") as j:
data = json.load(j);
xml = dicttoxml.dicttoxml(data)
print(xml)
I need to update (CRUD) a nested JSON file using Python. To be able to call python function(s)(to update/delete/create) entires and write it back to the json file.
Here is a sample file.
I am looking at the remap library but not sure if this will work.
{
"groups": [
{
"name": "group1",
"properties": [
{
"name": "Test-Key-String",
"value": {
"type": "String",
"encoding": "utf-8",
"data": "value1"
}
},
{
"name": "Test-Key-Integer",
"value": {
"type": "Integer",
"data": 1000
}
}
],
"groups": [
{
"name": "group-child",
"properties": [
{
"name": "Test-Key-String",
"value": {
"type": "String",
"encoding": "utf-8",
"data": "value1"
}
},
{
"name": "Test-Key-Integer",
"value": {
"type": "Integer",
"data": 1000
}
}
]
}
]
},
{
"name": "group2",
"properties": [
{
"name": "Test-Key2-String",
"value": {
"type": "String",
"encoding": "utf-8",
"data": "value2"
}
}
]
}
]
}
I feel like I'm missing something in your question. In any event, what I understand is that you want to read a json file, edit the data as a python object, then write it back out with the updated data?
Read the json file:
import json
with open("data.json") as f:
data = json.load(f)
That creates a dictionary (given the format you've given) that you can manipulate however you want. Assuming you want to write it out:
with open("data.json","w") as f:
json.dump(data,f)
I have the following json

}
which im trying to parse using the json module in python. I am only intrested in getting the following information out of it.
Name Value
operational-status Value
health-state Value
Here is what i have tried.
in the below script data is the json returned from a webpage
json = json.loads(data)
healthstate= json['response']['context']['operational-status']
operationalstatus = json['response']['context']['health-status']
Unfortunately i think i must be missing something as the above results in an error that indexes must be integers not string.
if I try
healthstate= json['response'][0]
it errors saying index 0 is out of range.
Any help would be gratefully received.
json['response']['context'] is a list, so that object requires you to use integer indices.
Each item in that list is itself a dictionary again. In this case there is only one such item.
To get all "name": "health-state" dictionaries out of that structure you'd need to do a little more processing:
[attr['value'] for attr in json['response']['context'][0]['attributes'] if attr['name'] == 'health-state']
would give you a list of of matching values for health-state in the first context.
Demo:
>>> [attr['value'] for attr in json['response']['context'][0]['attributes'] if attr['name'] == 'health-state']
[u'ok']
You have to follow the data structure. It's best to interactively manipulate the data and check what every item is. If it's a list you'll have to index it positionally or iterate through it and check the values. If it's a dict you'll have to index it by it's keys. For example here is a function that get's the context and then iterates through it's attributes checking for a particular name.
def get_attribute(data, attribute):
for attrib in data['response']['context'][0]['attributes']:
if attrib['name'] == attribute:
return attrib['value']
return 'Not Found'
>>> data = json.loads(s)
>>> get_attribute(data, 'operational-status')
u'ok'
>>> get_attribute(data, 'health-state')
u'ok'
json['reponse']['context'] is a list, not a dict. The structure is not exactly what you think it is.
For example, the only "operational status" I see in there can be read with the following:
json['response']['context'][0]['attributes'][0]['operational-status']
I post some JSON to a view. I want to now parse the data and add it to my database.
I need to get the properties name and theme and iterate over the array pages. My JSON is as follows:
{
"name": "xaAX",
"logo": "",
"theme": "b",
"fullSiteLink": "http://www.hello.com",
"pages": [
{
"id": "1364484811734",
"name": "Page Name",
"type": "basic",
"components": {
"img": "",
"text": ""
}
},
{
"name": "Twitter",
"type": "twitter",
"components": {
"twitter": {
"twitter-username": "zzzz"
}
}
}
]
}
Here is what I have so far:
def smartpage_create_ajax(request):
if request.POST:
# get stuff and loop over each page?
return HttpResponse('done')
python provides json to encode/decode json
import json
json_dict = json.loads(request.POST['your_json_data'])
json_dict['pages']
[
{
"id": "1364484811734",
"name": "Page Name",
"type": "basic",
"components": {
"img": "",
"text": ""
}
},
{
"name": "Twitter",
"type": "twitter",
"components": {
"twitter": {
"twitter-username": "zzzz"
}
}
},
}
]
I have this json object, and I am curious how to iterate through servicecatalog:name and alert for any name that does not equal "service-foo" or "service-bar".
Here is my json object:
{
"access": {
"serviceCatalog": [
{
"endpoints": [
{
"internalURL": "https://snet-storage101.example.com//v1.0",
"publicURL": "https://storage101.example.com//v1.0",
"region": "LON",
"tenantId": "1
},
{
"internalURL": "https://snet-storage101.example.com//v1.0",
"publicURL": "https://storage101.example.com//v1.0",
"region": "USA",
"tenantId": "1
}
],
"name": "service-foo",
"type": "object-store"
},
{
"endpoints": [
{
"publicURL": "https://x.example.com:9384/v1.0/x",
"tenantId": "6y5t4re32"
}
],
"name": "service-bar",
"type": "rax:test"
},
{
"endpoints": [
{
"publicURL": "https://y.example.com:9384/v1.0/x",
"tenantId": "765432"
}
],
"name": "service-thesystem",
"type": "rax:test"
}
]
}
If x is the above mentioned dictionary. You could do
for item in x["access"]["serviceCatalog"]:
if item["name"] not in ["service-foo", "service-bar"]:
print(item["name"])
ps: you could use json.loads() to decode json data if you are asking for that. And also you have errors in your JSON.
