IsValid regular expression question

[drforbin1970]

Would one of the following validate this input? Space/blank giving me trouble. Have tried :space: and :blank: also. Shouldn't the /s detect a blank space in the string?

<cfset y = " ">
<cfoutput>
<cfif IsValid("regular_expression", y, "[a-zA-Z0-9 ]+")>
1)#y#
</cfif>
<cfif IsValid("regular_expression", y, "[a-zA-Z0-9\s]+")>
2)#y#
</cfif>
</cfoutput>

Sorry about that, typo. I've corrected the code. But - still no luck. Any suggestions?

This is a bug with how CF interfaces to java's regex.
File a bug report.

The code below shows how bad the bug is plus a java work around.

<cfif IsValid ("regex", y, ' ')>
3 )#y#
</cfif>

<CFSET oPattern = createObject ("java", "java.util.regex.Pattern").compile ("[a-zA-Z0-9\s]+")>

<cfif oPattern.matcher (y).find ()>
4 )#y#
</cfif>
