My vugen script looks like
web_submit_data("getClassDetails_2",
"Action= websiteURL /getClassDetails",
"Method=POST",
"RecContentType=application/json",
"Referer= websiteURL /manage_schedules",
"Snapshot=t320.inf",
"Mode=HTTP",
ITEMDATA,
"Name=draw", "Value=1", ENDITEM,
"Name=columns", "Value=classSubtypeMaster.classSubtypeName,classSubtypeMaster.classSubtypeKey,divRegJson,finalWeekMapJson,finalWeekMapJson,createdOnDate,createdByUserId,scheduleClassMainKey,scheduleStartId.clndrDate,scheduleEndId.clndrDate,occrStartFiscalWeek,occrEndFiscalWeek,comments", ENDITEM,
"Name=order[0][column]", "Value=0", ENDITEM,
"Name=order[0][dir]", "Value=asc", ENDITEM,
"Name=start", "Value=0", ENDITEM,
"Name=length", "Value=10", ENDITEM,
"Name=search[value]", "Value=", ENDITEM,
"Name=search[regex]", "Value=false", ENDITEM,
"Name=nodeList", "Value=18", ENDITEM,
"Name=nodeIdList", "Value=3", ENDITEM,
"Name=searchColumns", "Value=classSubtypeMaster.classSubtypeKey,divRegJson,finalWeekMapJson", ENDITEM,
LAST);
before this step i am placing these below web_reg_save_param_ex functions
And i tried with the below web_reg_save_param_ex
1st Try
web_reg_save_param_ex(
"ParamName=scheduleClassMainKey",
"LB=onclick=\"openCalenderModal(event,",
"RB=)\" class=\"calenderPop\">",
"NotFound=error",
"Ordinal=all",
SEARCH_FILTERS,
"Scope=BODY",
"IgnoreRedirections=Yes",
LAST);
2nd Try
web_reg_save_param_ex(
"ParamName=scheduleClassMainKey",
"LB/RE=<a href=\"copySchedule?scheduleClassMainKey=",
"RB=&type=copySchedule\"><i ",
"NotFound=warning",
"Ordinal=all",
SEARCH_FILTERS,
"Scope=ALL",
"IgnoreRedirections=Yes",
LAST);
But getting error in output
1st Try output
Action.c(213): web_reg_save_param_ex started [MsgId: MMSG-26355]
Action.c(213): Registering web_reg_save_param_ex was successful [MsgId: MMSG-26390]

Action.c(224): Notify: Saving Parameter "scheduleClassMainKey_count = 0"
saving the parameters as lr_output_message("PC:%d",atoi(lr_eval_string("{scheduleClassMainKey_count}")));
and
2nd Try
Action.c(245): Notify: Parameter Substitution: parameter "scheduleClassMainKey_count" = "0"
Action.c(245): 0
Action.c(246): Warning:
Based on the comments tried but still getting below error in output pane:

Action.c(203): web_submit_data("getClassDetails_2") highest severity level was "ERROR", 177 body bytes, 510 header bytes, 11 chunking overhead bytes [MsgId: MMSG-26387]
Ending action Action.
can anyone tell me where am i doing wrong.

Answer 1

Both simplified versions of web_reg_save_param_ex successfully extract values from the provided response fragment.
web_reg_save_param_ex(
"ParamName=scheduleClassMainKey",
"LB=onclick=\"openCalenderModal(event,",
"RB=)\" class=\"calenderPop\">",
"Ordinal=all",
SEARCH_FILTERS,
"Scope=Body",
LAST);
web_reg_save_param_ex(
"ParamName=_scheduleClassMainKey",
"LB=<a href=\"copySchedule?scheduleClassMainKey=",
"RB=&type=copySchedule\"><i ",
"Ordinal=all",
SEARCH_FILTERS,
"Scope=Body",
LAST);
Output:
Notify: Saving Parameter "scheduleClassMainKey_1 = 393517".
Notify: Saving Parameter "_scheduleClassMainKey_1 = 393517".
Notify: Saving Parameter "scheduleClassMainKey_2 = 393528".
Notify: Saving Parameter "_scheduleClassMainKey_2 = 393528".
...
Notify: Saving Parameter "scheduleClassMainKey_count = 2".
Notify: Saving Parameter "_scheduleClassMainKey_count = 2".
Please, validate that you have not another errors/warnings in the replay log and that actual server response contains the expected html code.
Following your last update. This quote from replay log shows that the response body size was much smaller (177 bytes) relatively to provided response fragment.
Action.c(203): web_submit_data("getClassDetails_2") highest severity level was "ERROR", 177 body bytes, 510 header bytes, 11 chunking overhead bytes
Please, enable Extended log in Run-Time Settings that include "Advanced trace" and "Data returned by server" and run the script again to see whether the actual server response contains the expected data.

Answer 2

Are you saving both parameters to the same name "scheduleClassMainKey"?
Also,
According to the documentation:
The web_reg_save_param_ex function also supports array type parameters. When
you specify Ordinal=All, all the occurrences of the match are saved in an
array. Each element of the array is represented by the ParamName_index. See
Example of Parameter Arrays.
In the following example, the parameter name is A:
web_reg_save_param_ex("ParamName=A", "LB/ic=<a href=", "RB=\'>",
"Ordinal=All", LAST );
The first match is saved as A_1, the second match is saved as A_2, and so
forth. You can retrieve the total number of matches by using the following
term: ParamName_count. For example, to retrieve the total number of matches
saved to the parameter array, use:
TotalNumberOfMatches=atoi(lr_eval_string("{A_count}"));
Therefore the parameter you need to use is scheduleClassMainKey_1
