Dynamic Boundaries (LB & RB) in LR

If LB and RB are Dynamic…so you can perform the followings actions

Action_1 (Regular expression in Loadrunner)

1.

LB/DIG or RB/DIG

Can be used as (#) as a wildcard for a single digit.

2.

/ALNUM

LB/ALNNUM or RB/ALNUM

Can be used as (^) as a wildcard for a single alphanumeric character.

1.1    ALNUMIC to ignore case.

1.2     ALNUMLC to match only lower case.

1.3     ALNUMUC to match only upper case.

    

 Action_2:( web_reg_save_param)

e.g

Server respone =

“sever_name returned session_id_101=12bmklju789”so you  can visit or download site under the followings linke”

Assume …

LB is dynamic as session_id_101 is changing(101,102,103…) for each iteration.

Here we want to capture string as “12bmklju789”.

LB = “session_id_"

So use

saveOffset=3  ( Here 101,102 are changing so length of digit is 4 including "101=" )

saveOffSet = can be used to capture Left dynamic characters.

RB =” 

Finally it goes like ..

Web_reg_save_param(“sessionID”,

”LB= session_id_“,

“RB=\””,

“ORD=all”,

“SaveOffSet=4”,

    LAST);
