Separate content from a String

Separate content from a String

Hi All,

I have a form with a rich text field and a single record. The field contains email content

My second form sends a notification using the fields value as the body of the email, on success.

The problem I have is separating deluge (such as + input.anyfield +) from the HTML / content.

My code so far: 
  1.  EC = email_form[ID == 45644000002346541];
  2. req = EC.email_content.toString();
  3. sendmail
  4. [
  5. from :"zoho@zoho.com"
  6. to :"chris@zoho.com"
  7. subject :"subject for this email"
  8. message :req
  9. ]

is it possible to catch, then replace all to achieve this? 

Really appreciate any assistance.
