Stripping HTML from 1 field to another as part of a flow?

[Ben28]

I'm trying to create a flow, so when a Problem moves from RCA, a new PTASK is opened, and assigned to the Problem Owner to implement to corrective actions identified in the Fix Notes. I'm trying to pull fix_notes, (which is HTM enabled) from the Problem, and copy it to the PTASK description (which his plain text). I can get the fix_notes content to copy, but it comes over with all the html tags (<p>, < /br> etc.). I tried using a replace string transform function, within the flow, and using a regex to replace the string, but this results in a glide error when testing: com.glide.glideobject.GlideHTML@1e34d97. Is a transform the correct way to do this,, and if so, how, or is there a better way?

Tried with transformation function as well. Somehow, Replace String doesn't seems to work with html tags. Found an alternative and easy way to fix this. Please refer below steps :

1. Suppose I have a flow variable in which HTML is stored :

2. To get rid of the HTML tags, we will make use of Scripting and regex. With replace function, we will replace the HTML tags with a null :

var htmlString = fd_data.flow_var.accountnametocreate;
var plainText = htmlString.replace(/<[^>]+>/g,'');
return plainText;

 Output :

Hi, thanks for this, I got it somewhat working using "var htmlString = fd_data.trigger.current.fix_notes;" to pull the fix_notes details, and strip off the html. However, it is possible to replace the html line breaks with carriage returns? What I end up with currently, is 3 lines of HTML, all combined into 1. For example:

Corrective Action/Preventive Action Plan: Install more server memory

Change Required?: Yes/No

Tentative Implementation date: 

Becomes:

Corrective Action/Preventive Action Plan: Install more server memoryChange Required?: Yes/No Tentative Implementation date:

OK, think I got this working now. Had to add a new regex expression to replace <br> and <p> with /n first.

var ptaskinstructions = "This PTASK is to track CAPA Implementation.\n" +
"It can be reassigned to the team & person responsible for Implementation the actions identified in the RCA.\n" +
"Additional PTASKs can be created if required.\n";
var htmlString = fd_data.trigger.current.fix_notes;
const plainText = decodeHTML(htmlString);
//var plainText = htmlString.replace(/<[^>]+>/g,'');
combinedText = ptaskinstructions + plainText;
return combinedText;

function decodeHTML(str) {
var a = str.replace(/<br\s*\/?>|<p\s*\/?>/gi, '\n'); //Retain line breaks
var b = a.replace(/<\/?[^>]+(>|$)/g, ""); //Remove tags
var c = b.replace(/&amp;/g, '&'); //Retain any ampersands that are just ampersands
return c.replace(/&#(\d+);/g, function(match, dec) {
return String.fromCharCode(dec); //Returns the special character from the decimal code representation and returns the entire decoded string.
});
}
