CPI Groovy scripts mostly used

1. Convert xml to json
   This is mostly not required as we have standard step to convert the xml to json. In some cases, we might need to go for groovy script to handle this issue. 
2. Remove nodes with condition
   This is to get the input and apply condition to remove the nodes from the input file.
   
   
   <root>

   <emp>Test</emp>

   </root>
3. Merge two xmls 
   One example here would be let us say you fetch the data from two endpoint and finally, you want to merge these two, hence groovy script is used.
