Hello Everyone, I'm completely new to node-red. I am trying to create a flow in which i have to loop while condition and within loop i need to add sub flows based on value of loop. ※sub flows are the same handling. Input A zip file that inside contains many text files Output The result fil…

OK, quick question: Is the number of loops known? Silly question. The top inject node. That starts things happening. Though I guess the bottom one does stuff too. Is the number of loops you need to do known when you press the top inject button? Actually, why two inject buttons? I need to k…

Sorry for the confusing explanation. The picture above is just a draf illustrating what I was thinking. The end result is aggregated into an inject node. I want to pass an array of text files into a loop like msg.payload.length instead of the fixed 4 value of the while loop. Array of length 3, b…

Just a note, node-red is used to get a message from point a to point b with manipulation along the way: loops should be avoided when possible. Why is there a "need" for a loop ?

[image] bakman2: Why is there a "need" for a loop ? Need a loop because corresponding to the processing of each TXT file, if it fails, it will do other things such as output the file to the Error folder (1), send mail to report the error file (2), ... and this also needs to be done with the n…

You dont really need a loop - you need to change your perspective :wink: Perhaps this would work for you (I am uncertain what you intend to do with the templates so it may not work for you) Look maa - no loops ... [image] results... [image] [{"id":"910ee8fb.f36198","type":"debug","z":"ea150be4…

Thank you for your support! Need a loop because corresponding to the processing of each TXT file, if it fails, it will do other things such as output the file to the Error folder (1), send mail to report the error file (2), ... and this also needs to be done with the nodes of Node-RED. If ther…

[image] minhhn0205: Need a loop because corresponding to the processing of each TXT file Again, it is VERY likely you do NOT need to loop. You need to learn node-red. The "generate result output" node could be ANYTHING. It could be bunch of nodes that process a file, check it for errors, r…

[image] Steve-Mcl: This doesnt make a whole lot of sense. Can you explain with details? I am trying to write a flow that will extract a zip file containing TXT files, from the extracted TXT files, check the contents of each TXT file. If the checking file content fails, it will move the TXT f…

@minhhn0205 I know this can be very frustrating and I know people think differently. What you have said there is still vague. Sorry. So, reading what you said: You have a zip file. (contents TXT files.) @Steve-Mcl I only sort of get what you mean, but alas that too is a bit vague for me, let…

What are you struggling with? He says he wants to loop files - I said its not required (so did @bakman2 ) [image] minhhn0205: I am trying to write a flow that will extract a zip file containing TXT files, from the extracted TXT files, check the contents of each TXT file Like this (no loop) …
