Read data file with non local path

General
1

Hello...I need a function to read the content of a file that has a different path (it's located in app online),
the path is similar to this "data:text/plain;base64,c2FsdXQgICAuLmplIHN1aXMgSGFmc2EgQXJhYmJhdGU=", the 'file in' node can't recognize the path like this..So I'm wondering if I put this path as a variable in a function and read the file but I'm not good enough in JS ..any help?tst2

That is not a path. it is a bas64 encoded data

so you would split it at the comma and the base64decode everything after comma to get the text.

The file nodes (as you have found) only read local files. For web based resources you probably need the http-request node - but again that needs a proper url - what you have is an inline resource that is a base64 encoded piece of text. You would need to extract and decode the text first and then use that as a url.
