  private String getSubstitutedString(Map<String, String> valueMap, String beforeParsing) {

    VelocityEngine ve = new VelocityEngine();

    ve.init();

    VelocityContext context = new VelocityContext();

    StringWriter writer = new StringWriter();

    for (Map.Entry<String, String> entry : valueMap.entrySet()) {

      String value = xssApi.filterHTML(entry.getValue());

      value = Jsoup.parse(value).text();

      context.put(entry.getKey(), value);

    }

    ve.evaluate(context, writer, "VelocityParser", beforeParsing);

    return writer.toString();

    }

Here, the argument beforeParsing is the velocity syntax template String that contains condition based variables and its values will be replaced by actual values which are in Map.

As mentioned by Himanshu/Arun, this is not supported OOB but you can still use any template engine (client/server side) like  Velocity/Handlebars/Mustache etc. and get the results. You may also try for a PostProcessor if your use case requires it.

Hi,

I think its not possible with OOTB AEM templates, because you can't run javascript in mail(not supported in many mail client).

But you can set both Label and value in key and return "" if something is null.

You can use the Apache Velocity templating engine to add condition based Text in Email.

We had the same requirement once and utilised Apache Velocity Templating engine and it's quite nice.
