hi , Now my manual coreelation is also success . and am able to handle my token ID using Xpath.
seems i can proceed with the logic of extracting a substing and findout the actual value from substing.
i have used two functions like
lr_web_reg_save_param_xpath and
lr_get_values functions..
So please share thoughts if anyone usning anyother methods to extract a dynamic value from complex xml.
my methods are bit complex if different dynamic value with same left , right boundary.
