Summary: New function __Replace() for replacing some pattern in
string
Severity: enhancement
Classification: Unclassified
OS: All
Reporter: [email protected]
Hardware: All
Status: NEW
Version: 2.8
Component: Main
Product: JMeter
Hello!
I want ask, what you think about implementing new function for JMeter which
provide possibility for replacing of some pattern in a string?
I wrote a little example which implement that functionality, could you look at
it?
You can use it like:
______________________________________________________________________________________________________________________________________________________________________________
Example
|Result
_________________________________________________________________________________________________________________________|____________________________________________________
${__Replace(some_xml_big_data_with_#CustomerID#_and_another_else,#CustomerID#,3.15-9.20)}
|some_xml_big_data_with_3.15-9.20_and_another_else
_________________________________________________________________________________________________________________________|____________________________________________________
${__Replace(some_#FormatID#_big_data_with_#CustomerID#_and_another_else,#CustomerID#,3.15-9.20,#FormatID#,xml)}
|some_xml_big_data_with_3.15-9.20_and_another_else
_________________________________________________________________________________________________________________________|____________________________________________________
${__Replace(123456,5,7,3,9)}
|129476
_________________________________________________________________________________________________________________________|____________________________________________________
${__Replace(123456,[1-2],7,3,9)}
|779456
_________________________________________________________________________________________________________________________|____________________________________________________
${__Replace(123456789qwerty,[1-2],7,3,9,[w],word)}
|779456789qworderty
_________________________________________________________________________________________________________________________|____________________________________________________
in User defined variables
|
string = 123456789qwerty
|
${__Replace(${string},[1-2],7,3,9,[w],word)}
|779456789qworderty
