[Question]: How to properly extract text from BODY?

[Yakutoc]

Thanks for your answers and help.

I decided to do it differently.

I'll just cut out everything that comes after "### What/why сhanged"

"custom_placeholders": [  
  {  
    "name": "DESC",  
    "source": "BODY",  
    "transformer": {  
        "pattern": "(?:\n### What\/why сhanged)(.*)",  
        "flags": "s",  
        "target": " "  
    }  
  }  
]

The custom_placeholders use javascripts replace method.

As far as I can observe, I suppose you would expect it to use match instead?
(debugger preview with match in use, which would do what you expect)

Yep =)

I expected that 1$ is the result of a regular expression and that it will replace its BODY.

Is it even possible to do this?

Unfortunately the replace function of JavaScript works differently

You can best test its behavior here for example: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace

const paragraph = "## Release Notes\n\n### Dropdown\n\nsome text\n\n### What/why Changed\n\nsome text\n\nsome text";

const regex = /(?:## Release Notes)(.*)(?:### What\/why Changed)/s;

// this is the behaviour within the action
console.log("FIRST EXAMPLE");
console.log(paragraph.replace(regex, '$1'));

// this would be the result of match (which returns an array, and has no target)
console.log("SECOND EXAMPLE");
console.log(paragraph.match(regex));

// the index 1 result of the match array
console.log("THRID EXAMPLE");
console.log(paragraph.match(regex)[1]);

I would love to find a better solution with javascript which would work like match, and has the support for the "target" - as that would most of the times be the most convenient way of doing things.
