Split string

Greetings,

 

I have a need to split the following string from this:

1234_5678.901.A_1.jpg

to this:

1234_5678.901.A

If I use the following split function, it splits at the first '_', where I need it to split at the 2nd '_'

split(outputs('Get_File_Name'), '_')[0]

Is there a way to reference the second underscore in the split function?

Thank you; in advance!

 

Update - I resolved this by removing the second '_' in the generated filename and replacing it with a '-'.  I then used the following split function:

split(outputs('Get_File_Name'), '-')[0]

This works for my needs.

Hi @tianaranjo,

 

You could also take a try with expression to achieve your needs and don't need to replace '_' with '-':

split(outputs('Get_File_Name'), '_1.')[0]

@StephenM I'm not an expert so bear with me and if I get this incorrect, hopefully the others on this chain will correct me.  The '0' is referring to an index or location in the string.  Hopefully these links will help:

Optional. An integer that specifies the number of splits, items after the split limit will not be included in the array

@StephenM - within PowerApps, I was using Concatenate to join the fields with  the '_'.  I simply changed that to '-'.
