Anyone know how I might manipulate a long text area field in flow? Most functions don't support long text and it appears (not verified) that I can't do anything with a long text field without crashing. My hope was to read it in from an object, dissect it into a text collection (each small enough to work with), do some manipulation, then build back the long text element from the modified pieces, and write back. These long text fields are involved in something we do several times a week and editing them by hand is very error prone.
I have a subflow written long back that takes a string input (no designation inside flow on what type or how long) and breaks it up into a string collection. But the moment I try to pass in the long text field, it fails. Even when the string is short.
Your best bet is to ask Soapbox how they manipulate it. Apex doesn't have any standard HTML parser, so you would have to build your own or take a chance on this open-source class: https://github.com/derekweber/ApexHTMLParser
