StringRegExp in Groups

Recommended Posts

Hi,

What can be the shortest way to return (3) when passing "Wesley" or "Ingrid" (both in group 3) using StringRegExpReplace ?
Other names are not shortened for this no do example :

$iGroup = StringRegExpReplace("Wesley", ' "Renee,Eero,Maverick", "Chase,Seth,Sean", "Leonora,Wes,rid", "Jacob,Ashley,Rocket" ', ' 1.2.3.4 ')
MsgBox(0, "", "Wesley is in group - " & $iGroup

Thanks

Can you try to explain, in more detail, what it is you are trying to accomplish?  Also, please explain why the StringRegExpReplace function is so integral to the solution.

This works:

Local $sPattern = "^.*?(?:(Renee|Eero|Maverick)|(Chase|Seth|Sean)|(Leonora|Wes|rid)|(Jacob|Ashley|ocke)).*"
Local $sReplace = "('$1'=''?0:1)+('$2'=''?0:2)+('$3'=''?0:3)+('$4'=''?0:4)"
Local $iGroup = Execute(StringRegExpReplace("Wesley", $sPattern, $sReplace))
MsgBox(0, "", "Wesley is in group - " & $iGroup)
$iGroup = Execute(StringRegExpReplace("Ingrid", $sPattern, $sReplace))
MsgBox(0, "", "Ingrid is in group - " & $iGroup)
$iGroup = Execute(StringRegExpReplace("Rocket", $sPattern, $sReplace))
MsgBox(0, "", "Rocket is in group - " & $iGroup)

TheXman,
thanks for your response, I have chosen StringRegExpReplace as the candidate for this, simply because i know it deals with expressions and replacements for any needed modded returns ,one liner approach ,no arrays ,etc. , I only needed this example on how it can be done, wiz style :)

jchd,
Thanks I appreciate it, fits precisely with what i had in mind :)

Well, it will work nicely as long as there is no "rid" (for Ridley) in another group   :idiot:

I honestly forgot to mention that if i for instance passed  "ridge" it should return 3 as well :)

While in the proposed code the pattern may be easily derived from small-size input data, this "solution" is highly sensitive to possible collisions, as @mikell pointed out.

If the input is likely to be(come) much larger I'd recommend a completely different approach.

and so the plot thickens .. 
what can be changed to make it always look for the first match
Having "dge" in a group before or after "Rid" it always resolves to the "Rid" group ..

Local $sPattern = "^.*?(?:(Renee|Eero|dge)|(Chase|Seth|Sean)|(Leonora|Wes|Rid)).*"
;~ Local $sPattern = "^.*?(?:(Leonora|Wes|Rid)|(Chase|Seth|Sean)|(Renee|Eero|dge)).*"
Local $sReplace = "('$1'=''?0:1)+('$2'=''?0:2)+('$3'=''?0:3)"
Local $iGroup = Execute(StringRegExpReplace("Ridge", $sPattern, $sReplace))
MsgBox(0, "Ridge", "Ridge is in group - " & $iGroup)

That's precisely the fail case for this approach: unwanted collisions (as I just above).

Still you can mitigate some of these issues:

Local $sPattern = "^.*?(?:(Renee|Eero|.*dge)|(Chase|Seth|Sean)|(Leonora|Wes|Rid)).*"
Local $sReplace = "('$1'=''?0:1)+('$2'=''?0:2)+('$3'=''?0:3)"
Local $iGroup = Execute(StringRegExpReplace("Ridge", $sPattern, $sReplace))
MsgBox(0, "Ridge", "Ridge is in group - " & $iGroup)

jchd,
guess I somehow got over occupied to not think of trying that out for myself - no biggie :)

Thanks again
