ex ： {
"category": "fiction",
"author": "Herman Melville",
"title": "Moby Dick",
"isbn": "0-553-21311-3",
"price": 8.99
}
==>
{
"category": "fiction",
"author": "Herman Melville",
"title": "Moby Dick",
"isbn": "0-****-3",
"price": 8.99
}
if i match "isbn" node

Yes, there is. This example replaces all nodes named "isbn" with "0-****-3".

DocumentContext dc = JsonPath.parse("insert your json string here")
dc.put("$..isbn", "0-****-3");

If you'd like to replace only some nodes depending on their value you could use e.g. regular expressions inside the path:

$..[?(@.isbn=~/0-\d{3}-\d{5}-3/)].isbn
