Class ConvertorOperator

java.lang.Object

org.thales.punch.libraries.punchlang.operator.ConvertorOperator

public class ConvertorOperator
extends Object

The convertor operator transform a XML or Json input String into a punch tuple.

 
        convert("{ \"age\": 22}").into([result]);
 
 

produces

 
        result = {"age" : 22}
 

It works similarly with XML inputs. Say you have the following XML document in an input String

  
 <xml version="1.0" encoding="UTF-8">
 <breakfast_menu>
 <food>
     <name>Belgian Waffles</name>
     <price>$5.95</price>
     <description>
    Two of our famous Belgian Waffles with plenty of real maple syrup

     <price>$7.95</price>

 <food>
     <name>Homestyle Breakfast</name>
     <price>$6.95</price>
     <description>
     Two eggs, bacon or sausage, toast, and our ever-popular hash browns
     </description>
     <calories>950</calories>
 </food>
 </breakfast_menu>
 

Running the following code :

        convert([message]).into([result]);
 

produces the following tuple:

 {
 "result": {
 "breakfast_menu": {
 "food": [
 {
 "calories": 650,
 "description": "Two of our famous Belgian Waffles with plenty of real maple syrup",
 "name": "Belgian Waffles",
 "price": "$5.95"
 },
 {
 "calories": 900,
 "description": "Light Belgian waffles covered with strawberries and whipped cream",
 "name": "Strawberry Belgian Waffles",
 "price": "$7.95"
 },
 {
 "calories": 900,
 "description": "Belgian waffles covered with assorted fresh berries and whipped cream",
 "name": "Berry-Berry Belgian Waffles",
 "price": "$8.95"
 },
 {
 "calories": 600,
 "description": "Thick slices made from our homemade sourdough bread",
 "name": "French Toast",
 "price": "$4.50"
 },
 {
 "calories": 950,
 "description": "Two eggs, bacon or sausage, toast, and our ever-popular hash browns",

 "price": "$6.95"
 }
 ]
 }
