Regular Expression named capture group problem

[biddle]

Maybe something like this?

"([crs][0-9]{2})(_\1){2}dirt"


--test
pattern = @"([crs][0-9]{2})(_\1){2}dirt"
regex = dotnetobject "system.text.regularexpressions.regex" pattern
m = regex.match "c01_c01_c01dirt"
format "Matched text is [%]" (m.tostring())
format "regex.success == %\n" m.success


EDIT:

Oops, didn't see that "dirt" suffix was optional

Try...
"([crs][0-9]{2})(_\1){2}(dirt)?$"


pattern = @"([crs][0-9]{2})(_\1){2}(dirt)?$"
regex = dotnetobject "system.text.regularexpressions.regex" pattern
m = regex.match "c01_c01_c01dirt"
format "Matched text is [%]" (m.tostring())
format "regex.success == %\n" m.success
m = regex.match "c01_c01_c01"
format "Matched text is [%]" (m.tostring())
format "regex.success == %\n" m.success
m = regex.match "c01_c01_c01blah"
format "Matched text is [%]" (m.tostring())
format "regex.success == %\n" m.success
m = regex.match "c01_c01_c01dirty"
format "Matched text is [%]" (m.tostring())
format "regex.success == %\n" m.success

Cheers Mike, works great.

actually almost as soon as I posted I found out that it doesnt work how I need it to. the dirt part is optional after every c01. so all these would match:
c01_c01_c01
c01dirt_c01_c01
c01_c01_c01dirt
c01dirt_c01dirt_c01dirt
etc...

[biddle]

Try this one:

([crs][0-9]{2})(dirt)?(_\1(dirt)?){2}$


pattern = @"([crs][0-9]{2})(dirt)?(_\1(dirt)?){2}$"
regex = dotnetobject "system.text.regularexpressions.regex" pattern

tests = #(
"c01_c01_c01dirt",
"c01_c01dirt_c01",
"c01dirt_c01_c01dirt",
"s01_s01_s01",
"c01_c01_c01blah",
"c01dir_c01_c01dirt"
)

for t in tests do (
format "\nChecking [%]\n" t
m = regex.match t
if m.success then
(
format "Matched text is [%]\n" (m.tostring())
)
else
(
format "No match!\n"
)
)
