json_delete Function
Syntax
C result = json_delete(json as C, pattern as C)
Arguments
- jsonCharacter
Json to filter nested records from.
- patternCharacter
Pattern to match for deletion.
Description
Remove any nested array member that matches pattern.
Deletes attributes from a JSON string that match a certain pattern. For example, consider the following JSON string:
dim json as c = <<%json% { one : 1 , two : 2 , arr : [ { __deleted : true , fname : "joe" }, { __deleted : false , fname : "jim" } ], arr2 : [ { __deleted : false , fname : "joe" }, { __deleted : true , fname : "jim" } ], } %json%
Assume that you want to remove all 'rows' in the JSON that contain the attribute:
__deleted: true
Using json_delete() we can do this:
json = json_sanitize(json) 'convert to strict syntax dim json2 as c json2 = json_delete(json , "{ \"__deleted\" : true }") json2 = json_reformat(json2) ?json2 = { "one": 1, "two": 2, "arr": [ { "__deleted": false, "fname": "jim" } ], "arr2": [ { "__deleted": false, "fname": "joe" } ] }
