I already know the item (MAXI) exists, and I want to know which tag it is in.
In other words, I want to get (1001).
greetings
Show the full response content so we can see the structure returned.
Use a firebase query
Your ability to easily query your data is made more difficult by your use of AI2 lists as values instead of creating a firebase list (array) or creating sub nodes for each entry.
So if you ask for "PEDRO" you would be happy to receive the list 1003,1004?
if I request (MAXI), I should get (1001)
or
if I request (PEDRO), I should get (1003)
they are their container tags
but PEDRO has two entries...
Is your data insertion code insuring such duplication will never happen again, or did you just go back and fix that manually without following up on the duplication problem?
It won't happen again.
This was an example I took from a previous one.
You can do as in the attached example:
- convert the text to a csv string
- convert the csv string to a list
- search the list

@davidefa jumped the gun.
Here's mine.

Note:
I tested this with @davidefa 's JSON text block, and it turned out that was not JSON.
Unless the original web result comes back as JSON format, my sample is useless.

You have not yet learned how to call a value procedure?
enlighten me
The online book has moved.
You'll have to do some looking to learn about procedures.
Set Label1.Text to call tag ('PEDRO')
If you examine the blocks in @davidefa aia sample you will see he also packages up his logic in a value procedure and loads his labels by calling the procedure twice.
Download a blocks image of where he does that and post it here for the board, to show you understand.
You probably will need a List Picker or Listview to offer the app user the opportunity to to select a name from the Web query result content.
As previously suggest by me, IMHO, the best way to handle this is to use the power of Firebase queries, and to store your data on Firebase in a Firebase way.
Firstly, stop storing a list in the way you are doing it, and store your list data in an array on firebase. You can do it like this:
Now you see that all your data is accessible for Firebase querying.
You must set an index for the name you wish to query, in your rules, which in this case is "0":
"prueba5": {
"read": true,
"write": true,
".indexOn": "0"
}
Now you can query the data under prueba5 based upon the values in "0", and return the node/key for that value:
The situation is this:
The storage unit was positioned horizontally, and I changed it to a vertical position.
I actually got this from a previous example, but the issue is already resolved.
Thanks.
Yes, thanks. TIMAI2
The thing is, it was easier to copy the content for other activities when it was laid out horizontally;
doing it vertically is more tedious
thanks.
