Want to create a tabular report from Java using JSON file. I have an 861 kb Json report with me.
Kindly suggest me the approach need to be followed.
It sounds like your input is JSON. You did not specify an output format. But similar as in HTML you could place tabular data into JSON as well. Assuming that is the case, all you need is a JSON parser/serializer and inbetween some Java code to adapt one format for the other.
To transfer one XML data structure into another XML data structure there are nice tools like XSLT. Some of the implementations can also be used for JSON documents. See https://stackoverflow.com/a/49011455/4222206
With the above assumption your code would perform these steps:
Parse input JSON
Run XSLT for JSON
Serialize the obtained output

First I want to say I checked this nice question:
JSON to JSON transformer
I want to do something similar, however, I would like to know if there is a solution that will generate the transformation automatically, knowing I have an Input.json and a Output.json sample available at hand.
So I would give the program both json (input, output) and it generate for me the JsonPatch transformations that were done so that input + transformation = output.
Maybe this tool does not exist, but it would save me a lot of time! In java would also be a big plus :)
I wanted to parse x12 format file to json file using java.
I didn't find any information regarding this on internet.
can someone please tell me how to do this or any jar file which can be able to do this is also fine.
How to do it:
Obtain documentation on your x12 file (do you mean HIPAA data exchange?). It will tell you about the different records, their layout and sequencing
Define target schema for the JSON you want to produce. Surely you don't want to produce just any JSON
Define mapping. Draw spaghetti on a whiteboard, piece of paper, or something like Altova Mapforce, until you have all elements connected.
Choose your transformation approach depending on the dataset size - streaming or object to JSON serialization
Implement
Look for performance bottlenecks. Introduce optimizations to speed up processing.
I'm creating a tool which will take any XML as input and display it as a tree structure in the web page. Since anyone will be able to input their XML files to my tool, I will not know the XML schema in advance and I cannot create any JAXB classes. I will be parsing the XML using SAX parser and I need to store the contents of the XML in some data structure, so that I can do some processing on the XML data before I display it as a tree. But I'm not sure which data structure to use. I thought of using a Map of Maps kind of structure, but it becomes too complex. Could someone please suggest some ideas for the same ?
There is no code to share as it is still in the design phase.
EDITED:
This tool should display the XML elements as editable forms in the UI. The Element Names should be labels and the values should be displayed in an editable text box. Anyone should be able to edit the values and download the modified XML file. So I should parse the XML from java side and save it in some data structure and send it to UI, where I will be iterating the data structure and displaying it as an editable tree.
Sounds like you need a DOM parser which has a data structure for any XML document. This has a data model for XML.
If you need to store all the information in it's original state, a SAX parser won't help you.
I am attempting to parse a KML file which has some non-standard tags:
<Placemark id="plot">
<Type1> Type 1 </Type1>
<SA>62</SA>
<Type2> Type 2 </Type2>
I'm attempting to read/parse the file, obtain the representative elements as described above and then all the coordinates, and finally write the output to a text file for downstream use. I'm able to parse the file and get the coordinates with no issues but have been unable to determine a way to get the custom elements, and I need the data to format the output file correctly. The elements are not wrapped in an extendeddata structure or any other grouping.
I am hoping someone has run into this before and can offer some guidance on the best way to read the data via supplied methods for javaapiforkml.
You can have a look at OSMBonusPack KML parser, mainly here.
It's open source, so you can pick the classes you need, remove all Android-specific features, and add handling for your custom tags.
I am trying to figure out a way to produce test execution charts from cucumber produced JSON.
I looked into JFreeChart and would like to know if there a way to use JSON as input for JFreeChart or other java library.
JFreeChart won't read your JSON format data out-of-the-box, so you'll need to write your own code to process the JSON file/string and populate a dataset accordingly. I did something like this recently for Orson Charts, and used json-simple to do the JSON parsing. Of course, the code I wrote parses only a very specific set of JSON formats. I don't know the details of the "cucumber produced json" that you need to process, but hopefully the json-simple project can help you to get it done.
