Join an array within an array (RSS)

Hi, I'm trying to make a flow to get an RSS feed, then, because RSS potentially has multiple categories or links, I want to "join" the array to flatten it out. But I can't invoke "join" to combine the RSS categories or links. Any ideas how I can get "join" to work against "feed links" or "feed categories"?

Hi @jhuynh1 ,

 

Could you please explain more details about your requirement?

I'm afraid that your couldn't meet your needs with join expression in flow.

Please refer to link below to learn more about the join expression:

Thank you, do you know if there's another function that can achieve what I want (to condense the results of an array to a single string)?

Hi @jhuynh1 ,

 

Could you please take a try with expression string()?

If the expression string() couldn't meet your needs, I afraid that there is no any way to meet your needs with microsoft flow.

 

Best regards,

Thanks for looking at this! I can't invoke string, because only "RSS Body" shows up as an option when I use the Apply to Each.
