Perhaps you should explain what you are looking for, as your result is empty, ours will be too.

</div>

Here is an example

```auto
[{"id":"0ccc963f1de2b66d","type":"inject","z":"da8a6ef0b3c9a5c8","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":120,"y":660,"wires":[["5f25653eb6e92199"]]},{"id":"5f25653eb6e92199","type":"http request","z":"da8a6ef0b3c9a5c8","name":"","method":"GET","ret":"txt","paytoqs":"ignore","url":"https://tarifaluzhora.es/","tls":"","persist":false,"proxy":"","insecureHTTPParser":false,"authType":"","senderr":false,"headers":[],"x":270,"y":660,"wires":[["7e74615199be95f2"]]},{"id":"7e74615199be95f2","type":"html","z":"da8a6ef0b3c9a5c8","name":"","property":"payload","outproperty":"payload","tag":"span.col-sm-12","ret":"text","as":"single","x":500,"y":660,"wires":[["441b83f51eec6037"]]},{"id":"441b83f51eec6037","type":"debug","z":"da8a6ef0b3c9a5c8","name":"debug 116","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":650,"y":660,"wires":[]}]

```

The selector used

```auto
span.col-sm-12

```

Output

```auto
0.18617
€/kWh

```

Closing this thread since you opened [another thread](https://discourse.nodered.org/t/sorting-a-string/72739) asking the same thing.
