How about something like:

XSLT 1.0

This, @mohan, is a tricky one and I took it on as a challenge to myself. There is a way to update a nested JSON object's value like you're asking, however, it's not as straight forward as it seems.

Because you're working within an array, you need the array's index in order to update a nested value. In your case you don't know the index within the array, however, you do have a key-value you can reference, in this case, your feedName.

In order to update your value, you first need to "unpack" your JSON so that you can filter for a specific feedName, "ccsdcdscsdc" in your example.

Here is an example that you can run in SSMS that will get you moving in the right direction.

The first thing I created was @Customers TABLE variable to mimic the data structure you showed in your example and inserted your sample data.

the result in my javascript code is always No 'Access-Control-Allow-Origin'.

Well, the error is pretty clear the backend is not allowed to answer to CORS request if you own the backend you have to allow CORS (take a look to this documentation).
Otherwise, you need to ask the backend owner to allow the CORS requests.

With a minor modification, your XSLT file will work well. I added a variable to designate the file name of the program input data as well as the program output data. So the XSLT could look like this:

If I have understood correctly, the goal is to create gzip compressed data dynamically, without creating a file on the server. This is possible with deflate_init and deflate_add, but requires PHP 7.

Usually you should at least try something before posting a question on Stack Overflow, but since it's one of your first posts, I don't want to be rude so here's a full answer.

Using the standard xml library you can do this very easily.

Here's an example for exactly the behavior you described:

You need to read the file as an XmlDocument to be able to loop nodes. The loop would also have to loop nodes in the xml-object (not the input-path) and reference the current node inside the scriptblock. Try:

So if we have the XML string in $string, we can parse it into an XML object with simplexml_load_string:
