alert matching should be changed

[splint3rsec]

freq only checks if the string "alert(1)" is reflected in the result, which could lead to a lot of false positives, it would be great if the following block of code

sb := string(body)
   check_result := strings.Contains(sb , "alert(1)")

is changed to match "><img src=x onerror=alert(1)> or any other xss payload that contains < and > in order to avoid false positives.

Thanks
