Hi! We had a myForm.html file (accessible only from the third party) where in we needed to update the form containing input\/select\/check boxes with the values we had in the request params and then render it. So we used xmlslurper for the same. Without much effort, it just worked great. Following is the code we wrote:<\/p>\n
