Hi!
I have a problem with JSONUpdater and the function "Delete From Array".
My case :
I have this JSON file
I want to delete the value 79240 in "structure_ids". In JSONUpdate, I can't write the value, it doesn't work.
I do write the position of this value.
How can I do this dynamically? Is there an IndexOf function on FME?
And when I write a position, here 4, in JSONUpdater, it removes 2 values instead of one (79240,79389).
Thank you for your help

Hi @lribot
If you're familiar with XQuery, you can use the index-of function, as our XQuery transformers such as the XMLXQueryExtractor supports JSONIq extension.
If you prefer not to use XQuery, it should be possible using a JSONFlattener and ListSearcher. However, this method would not be suitable if there are multiple instances of 79240 as the ListSearcher only matches the first instance.
+31Using the index of position 4 should work here and it does correctly for me with your example.
Do you definitely only have one feature going to the update port?
hi edygomm! you're right, i have two feature going to the JSONUpdater. Now I have only one and it removes 1 value in my array.
Do you have an ideas how I can get the position of a value in an JSON array?

I don't know an FME way, I would probably end up resorting to python to remove the value from the array
