Set replacement text in IRedactionCallback

I want to change original text with replacement text using RegexRedaction where I need to decide replacement text based on original text as well after matched by pattern. I am looking for something like below.

IRedactionCallback ip = e -> {
          if(e.getOriginalText().startsWith("99")) {
              e.getReplacement().setReplacement("[override]");
          }
          return true;
  };
Redactor redactor = new Redactor(indoc, loadOptions, new RedactorSettings(ip);
RegexRedaction r = new RegexRedaction("\d+{4}", new ReplacementOptions("[default value]"));

In general, you need as many text redactions (e.g. regular expressions) as many replacements you have. For your scenario, the following approach will work:

Redaction []redactions = new Redaction[] {
    new ExactPhraseRedaction("9999", new ReplacementOptions("[override]")),  
    new RegexRedaction("\\d{4}", new ReplacementOptions("[default]")),
};
RedactorChangeLog result = redactor.apply(redactions);

Please note that in this case order is important, the first approach (ExactPhraseRedaction) applies first.

Hi @Atir_Tahir, my requirement is to do some complex operations like making API call and using the response of it to replace original text. In my case I can’t use static strings as replacement option, I need to get replacement text dynamically. Is there any extension point for that?

There is no option to change the replacement value in process of redaction. However, if you share a detailed overview of your use-case or business logic, we may offer a workaround.

Hi I know its a very old post but I still working with groupdocs and this requirement came up again. Below is my use-case and please suggest if its possible in groupdocs redaction library.

I have office documents which I have to redact but replace original text with encrypted as replacement value.
I use regex based redaction and currently I can get the actual text that is matched but can’t encrypt that text and set as replacement value. Is there a way to achieve it.

Gracias,
