Hi,

=============================

How to delete the key "x" in a json attribute by JsonUpdater transformer:

{ "x" : "aa", "y" : "bb" }

=============================

I send the feature both into the ports of "Document" and "Update", and set

Update Type: "Delete From Object"

JSON Path: json[*]

Object / Array Index: x

=============================

but get warnings below:

2016-06-16 17:27:38| 0.2| 0.2|WARN |JSONUpdater(XQueryFactory2): The following error occurred while executing query number 1:

2016-06-16 17:27:38| 0.2| 0.0|WARN |JSONUpdater(XQueryFactory2): The following error occurred near line 3, column 21 of the query:

2016-06-16 17:27:38| 0.2| 0.0|WARN |JSONUpdater(XQueryFactory2): xs:string can not be promoted to parameter type json-item() of function json-item-accessor()

=============================

Thanks

Hi @endest, json[*] indicates any member belonging to the root value, so your setting means "remove x from any member object contained by the root". You can set just json to the JSON Path to indicate the root. Try this.

  • JSON Path: json
Works fine!

And again... Takashi saves my day ;-)

I started off with json[*] and no result, but now it makes sense...
