I need to extract NSID from a list of string which is stored in a file.the string look like this.
the string inside jsonFlickrApi() is in json format.
007rebecca#gmail.com|jsonFlickrApi({"user":{"id":"21849273#N06", "nsid":"21849273#N06", "username":{"_content":"eire5555"}}, "stat":"ok"})
If I want to parse this and get the nsid, in java what approach i should take.
Should I write a parser or is there any library available to parse this json inside jsonFlickrAPI()
The string is a mix of a json and some other text. You may try to split the json part and then can use a json parser to retrieve nsid easily.There are various java json parsers available such as GSON.

How to convert sample JSON given below to a MT940 txt file:
This JSON would be a bad sample to show but hope you get the gist of it...
Just like we have a library in place to parse MT940 strings/txt we also have a library which can help construct a MT940 txt file in Java.
{
"accNumber":"123356",
"openBalInd":"D",
"openBalaDate":"200605",
"curr":"Dollar",
"transactions":[
{
"amount":""434,
"credit/debit":"1000",
"datetime":"20042020"
},
{
"amount":""434,
"credit/debit":"1000",
"datetime":"20042020"}]
}
MT940 is SWIFT message type.
Your input is JSON and the output is MT940 text file.
It is always good to have some java model classes representing your json.
Deserialise json input using Jackson to model you gonna use internally.
Use your own library or some third party like https://www.prowidesoftware.com/resources/SWIFT-writer to convert your internal model to MT940
Serialize the result into text file.
I am writing an application/class that will take in a template text file and a JSON value and return interpolated text back to the caller.
The format of the input template text file needs to be determined. For example: my name is ${fullName}
Example of the JSON:
{"fullName": "Elon Musk"}
Expected output:
"my name is Elon Musk"
I am looking for a widely used library/formats that can accomplish this.
What format should the template text file be?
What library would support the template text file format defined above and accept JSON values?
Its easy to build my own parser but there are many edge cases that needs to be taken care of and I do not want to reinvent the wheel.
For example, if we have a slightly complex JSON object with lists, nested values etc. then I will have to think about those as well and implement it.
I have always used org.json library. Found at http://www.json.org/.
It makes it really easy to go through JSON Objects.
For example if you want to make a new object:
JSONObject person = new JSONObject();
person.put("fullName", "Elon Musk");
person.put("phoneNumber", 3811111111);
The JSON Object would look like:
{
"fullName": "Elon Musk",
"phoneNumber": 3811111111
}
It's similar to retrieving from the Object
String name = person.getString("fullName");
You can read out the file with BufferedReader and parse it as you wish.
Hopefully I helped out. :)
This is how we do it.
Map inputMap = ["fullName": "Elon Musk"]
String finalText = StrSubstitutor.replace("my name is \${fullName}", inputMap)
You can try this：

Fastjson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object. Fastjson can work with arbitrary Java objects including pre-existing objects that you do not have source-code of.
I want to get the data from DB using stored procedures in the form of JSon file.
In simple words , my output should be json file which should be result of data in DB(based on stored procedure) .How can i move forward?
You have to create Object Mapper which will convert your data to an object (I think there's an apache library that can do this). Then you can use existing APIs to convert your objects to JSON string example of this is Google's or Jackson. When you have the JSON string you can now write it to a file. Hope this helps.
I'm trying to convert a JSON string to XML using jsonlib in Java.
JSONObject json = JSONObject.fromObject(jsonString);
XMLSerializer serializer = new XMLSerializer();
String xml = serializer.write( json );
System.out.println(xml);
The error that I get is
nu.xom.IllegalNameException: 0x24 is not a legal NCName character
The problem here is that I have some properties in my JSON that are invalid XML characters. eg. I have a property named "$t". The XMLSerializer throws the exception while trying to create a XML tag in this name because $ is not allowed in XML tag names. Is there any way in which I can override this XML well formedness check done by the serializer?
First I'd suggest to add the language you are using (it is Java, right?).
You could override the method where it checks your XML tag name to do nothing.
I took a look at the spec for the json-lib XMLSerializer and to my surprise it seems to have no option for serialising a JSON object whose keys are not valid XML names. If that's the case then I think you will need to find a different library.
You could loop over json.keySet (recursively if necessary) and replace invalid keys with valid ones (using remove and add).
I am having a really challenging time parsing some XML data returned to my Android app.
The data is sent as XML but printing it on my mobile screen, it comes out as the following:
{"sessid":"5eed0b52c6953b52e262b559b5557be4","session_name":"SESS6cbf091341a26e4687fa7850b465755a,"user":{"uid":"15","name":"guest","pass":"084e0343a0486ff05530df6c705c8bb4","mail":"adeoduye#hotmail.com", "mode":"0","sort":"0","threshold":"0","theme":"","signature":"","signature_format":"0","created":"1306008217","access":"1306094503","login":"1306134979","status":"1","timezone":"3600","language":"","picture":"","init":"adeoduye#hotmail.com","data":a:1:{s:13:\"form_build_id\";s:37:\"form-49ea7a4ef10a8a2b31478696f17e8dee\";","form_build_id":"form-49ea7a4ef10a8a2b31478696f17e8dee","roles":{"2":"authenticated user","3":"guest"}}}
Can anyone please help a newbie and give me some ideas on how to parse this type of output and/or plain XML?
This isn't XML but JSON. You have to parse that string using the JSON API.
Basically you create a JSONObject by feeding the string into a JSONTokenizer. You can now query the values from the JSONObject as described in the API reference example.
The String you're seeing here is in JSON format. You can parse this in Andriod using the following library : http://code.google.com/p/google-gson/
