> A method, that can replace strings (keys) in a file would be very useful. 
> For example if you have a file with the following text:
> {noformat}
> The packet must arrive between @dateFrom and @dateTo. 
> {noformat}
> You can now replace the "keys" with a value of your choice..
> Perhaps something like this:
> {code}	
> public static void replaceStrings(File inputFile, File outputFile, List<KeyValuePair<String, String>> replacements) throws IOException{
> 		BufferedReader in = new BufferedReader(new FileReader(inputFile));
> 		BufferedWriter out = new BufferedWriter(new FileWriter(outputFile));
> 		
> 		String line;
> 		
> 		while ((line = in.readLine()) != null) {
> 			for(KeyValuePair<String, String> kvp : replacements){
> 				line = line.replace(kvp.getKey(), kvp.getValue());
> 			}
> 			out.write(line);
> 			out.newLine();
> 		}
> 		out.flush();
> 		out.close();
> 		in.close();
> 	}
> {code}
> I think it should also be possible, to replace the strings in the inputfile so you don't have to create a new file (outputfile)
