Can we write regular expression in expression builder.
Just curious to know if we have any support for regular expression in Pega.
I mean can we write a when rule which checks for Words starting with ABC/123 etc..

Hi Nalin,
Please find the format for the expressions mentioned above
For pxReplaceAllViaReger
pxReplaceAllViaRegex(Param.ContentMessage, "[?, *, <, >, |, : ]", " ")
Param variable which is mentioned in the function contains the string with special characters.I have instructed function to replace the special characters.So, output of the funtion will be the string without special characters
For pxContainsViaRegex
@pxContainsViaRegex(.pyRuleSetVersion, "[0-9][0-9]\\-[0-9][0-9]\\-[0-9][0-9]", false)
funtion will check whether the attribute pyRuleSetVersion contains the pattern.Depends on match or unmatch you will get boolean output.

Hi
Thanks for the quick reply. I am trying to use @pxContainsViaRegex(Param.PropertyName, "[?,.*<>\/|:]",true)
Then above is used to check if the Property has any of the Characters, then return a value true. But i am getting error for using the special characters. Is the expression correct.
Thank you
