public class SimpleTemplater
extends java.lang.Object

To process simple HTML templates. -- Usage -- SimpleTemplater.getInstance().buildOutputUsingStringTemplate(template, parameters); Replaces ${parameter_name} in the template by its value found in the (Map)parameters. -- Syntax -- Simple blocks can be processed. Blocks are surrounded by and $$for(parameter_name) will loop over the items of parameter_name of type Collection> $$if(parameter_name) will execute only if parameter_name is defined and not empty $$ifnot(parameter_name) will execute only if parameter_name is not defined or is empty -- Example -- String template = " Dear ${name}, Here is the list of your things: ${name} Regards, Sincerely, Me"; Map parameters = new HashMap(); parameters.put("name", "You"); parameters.put("regards", "1"); Collection> things = new ArrayList>(); for (int i=0; i<3; i++) { Map p = new HashMap(); p.put("name", "Thing + i); things.addElement(p); } parameters.put("things", things); String output = SimpleTemplater.getInstance().buildOutputUsingStringTemplate(template, parameters); System.out.println(output);
