Parsing txt file


Hello there , I am new to Node-red and I`d like to know how do I can parse text from a file and display it on my dashboard ... My dashboard is ready and working but idk how to parse the "Menu1" word from my txt file ... the first node that opens the file works (the entire content of the file appears in the debug) but still cant parse a word in ...
Here is the code in my parsing node ;

if (!context.count){
context.count = 20;
parsed = parseInt(msg.payload);

msg.payload = context.count;
return msg;

and here is the debug tab :

03/04/2019 à 11:02:45node: 9fb6b5f3.404608
msg.payload : string[29]
"Menu1 \t fasfdfds \t fghsd \t"
03/04/2019 à 11:02:45node: 40c35d07.249254
msg.payload.variable_1 : undefined

as you can see , it can read in the file but dont recognise the word "Menu1" in it..
Thanks for help and spending your time reading this

here is the parsing flow :

[{"id":"9aed556e.760008","type":"tab","label":"parse","disabled":false,"info":""},{"id":"b2db9145.f5b1","type":"inject","z":"9aed556e.760008","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":420,"y":80,"wires":[["a3ab124e.5f21a"]]},{"id":"a3ab124e.5f21a","type":"file in","z":"9aed556e.760008","name":"access to file","filename":"/home/pi/Desktop/sms/messages","format":"utf8","chunk":false,"sendError":true,"encoding":"utf8","x":170,"y":180,"wires":[["9fb6b5f3.404608","a8c43f28.32aed"]]},{"id":"881d70a9.606ec","type":"function","z":"9aed556e.760008","name":"recherche du mot Menu1","func":"if (!context.count){\n context.count = 20;\n}\nparsed = parseInt(msg.payload);\nif(parsed==1){\n context.count++;\n }\n\nmsg.payload = context.count;\nreturn msg;\n","outputs":1,"noerr":0,"x":510,"y":160,"wires":[]},{"id":"40c35d07.249254","type":"debug","z":"9aed556e.760008","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload.variable_1","targetType":"msg","x":450,"y":360,"wires":},{"id":"9fb6b5f3.404608","type":"debug","z":"9aed556e.760008","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","x":370,"y":40,"wires":},{"id":"a8c43f28.32aed","type":"function","z":"9aed556e.760008","name":"parsing "Menu1"","func":"if (!context.count){\n context.count = 20;\n}\nparsed = parseInt(msg.payload);\nif(parsed==1){\n context.count++;\n }\n\nmsg.payload = context.count;\nreturn msg;\n","outputs":1,"noerr":0,"x":330,"y":260,"wires":[["40c35d07.249254"]]}]


I’m on my phone so can’t import your flow.

But assuming your parsing node is a function, you aren’t using the newer syntax for context values.


You can also see the Logging events part of the same page for how to log events from within a function so you can see what your function is doing


yes thanks , but i dont really know what I should use ,Im a very beginner with node-red


Which is why I posted a link to the docs that include examples
