Explain replace function in QTP with Example.

Replace function is used to replace the part of the given string with other sub string in QTP.

Example -


myString = "Sachin plays cricket"


print replace(myString,"Sachin","Dhoni")
'Will print Dhoni plays cricket

print replace(myString,"sachin","Dhoni")
'Will print Sachin plays cricket. Because we have used sachin in small case letter

print replace(myString,"sachin","Dhoni",1,-1,0)
'Will print Sachin plays cricket .....Same as above

print replace(myString,"sachin","Dhoni",1,-1,1)

'Will print Dhoni plays cricket....
'The last parameter of replace determines whether the replacement is case-sensitive or case-insensitive.
'If last parameter is 0, replacement is case-sensitive
'If last parameter is 1, replacement is case-insensitive
