Though asked, it has never been answered.  
Can you do an import/require in an Evaluate Flow block to use xml2js?

In a post-response script, I can use  
const xml2js = require(‘xml2js’);

In the Evaluate block it errors. I’ve tried  
let xml2js = import(‘xml2js’);

but that does not seem to work. There is no error, but once I reference xml2js.parseString, there is an error about the function.

import and require are not supported today in evaluate blocks. We’re considering this for the future.
