How to correlate a value with dynamic boundaries in VuGen

If you are checking this post, seems the left and right boundaries are killing your time. Lets check how to deals with those dynamic boundaries using the text flags of VuGen.


You can use one of the following flags after the text, preceded by a forward slash:
/IC to ignore the case.
/DIG to interpret the pound sign (#) as a wildcard for a single digit.
/ALNUM to interpret the caret sign (^) as a wildcard for a single US-ASCII alphanumeric character. There are three syntaxes: ALNUMIC to ignore case, ALNUMLC to match only lower case, and ALNUMUC to match only upper case.

eg: email\u003d\"notification+mkuw__3d@facebookmail.com
In the above server response if you have to capture the highlighted part(in RED), the left and right boundaries have some alphanumeric chars and if they are dynamic then you have to follow the below approach.

web_reg_save_param("account_notify",
        "LB/DIG=email\u00#d\\"",
        "RB/DIG=__#d@facebookmail.com",
        "Ord=1",
        "Search=Body",
        LAST);

and for instance lets say that "u003d" in the left boundary itself is dynamic, then below will be our approach.

web_reg_save_param("account_notify",
        "LB/ALNUMIC=email\^^^^^\\"",
        "RB/DIG=__#d@facebookmail.com",
        "Ord=1",
        "Search=Body",
        LAST);

ALNUMIC means the boundary is an alphanumeric and IC asks it to ignore the case(upper or lower)
