Dynamic Correlation in Opensta

Dynamic Location in OpenSTA
If in a particular application you need to fetch the parameter values from HTTP Requests for correlation and position of the parameters is not fixed in page, In this case you can not rely on HTML DOM addressing.
OpenSTA has its ability to fetch the values dynamically,
Following is the sample code for that:
Where you need to supply the left & right boundary with Page Response, by using Locate & Extract it will fetch the values
! Standard Defines
CHARACTER*65535 ServerResponse, LOCAL
CHARACTER*65535 parameter, LOCAL
INTEGER Offset
CHARACTER*512 RIGHT_BOUNDARY, LOCAL
CHARACTER*512 LEFT_BOUNDARY, LOCAL
! OpenSTA Code
LOAD RESPONSE_INFO BODY ON 1 INTO ServerResponse1
! Loading the page response into variable please check the connection ID should
! Be same as in request
IF (ServerResponse1 = "") THEN
Log " Error in Page No Data Available”
Detach Thread
ENDIF
SET LEFT_BOUNDARY=''
CALL FetchByDynamic [ServerResponse1, LEFT_BOUNDARY, RIGHT_BOUNDARY]
SET viewstate = parameter ! Set the Fetching value in required parameter
!*******************************************************************************
SUBROUTINE FetchByDynamic [ServerResponse, LEFT_BOUNDARY, RIGHT_BOUNDARY]
SET offset= ~LOCATE (LEFT_BOUNDARY, ServerResponse)
IF (offset <= 0) THEN
LOG “ERROR at OFFSET while Fetching value”
REPORT “ERROR at OFFSET while Fetching value ", ServerResponse
Detach Thread
ENDIF
SET offset = offset + ~LENGTH (LEFT_BOUNDARY)
SET parameter = ~EXTRACT (offset, 65535, ServerResponse)
SET offset=~LOCATE(RIGHT_BOUNDARY,parameter)
SET parameter = ~EXTRACT (0, offset, parameter)
RETURN
END SUBROUTINE
!*******************************************************************************
Limitation:
If page response is greater than 64k in that case if required parameter value is not within 64k then it will not able to capture the values, As page can be loaded of maximum 64k in variable.
Also while implementing this code please crosscheck from page response that required value is set properly.
