Hi there,  
i tried to extract a value from a httprequest. The Value changes every second.  
When i make the request :  
[http://blynk-cloud.com/RUAYzVsCN7uQIIlUYc2DFjiCOq5XyZnN/get/V3](http://blynk-cloud.com/RUAYzVsCN7uQIIlUYc2DFjiCOq5XyZnN/get/V3)  
i get back ["11.730"].  
I only want to further processing the value without [""].

Get a hint on facebook to use node-red-contrib-string but i was unsuccessful

Could someone help?

Regards

Send the message through a JSON node then use the copy path button that appears in the debug message when you hover the item of interest.

Ps, you don't need that string node, the payload is valid JSON & therefore can be converted to an actual js object for easy access to it's elements.
