Hello,

I'm having a hard time with regex.
I need to isolate parts with a certain color in a RTF field.
Here is my source :
Quote


{\
tf1\ansi\ansicpg1252\deff0\
ouicompat\deflang1033{\onttbl{\0\nil\charset0 Tahoma;}}

{\colortbl ;\
ed0\green0\lue0;\
ed64\green85\lue141;\
ed0\green30\lue196;}

{\*\generator Riched20 10.0.17134}\viewkind4\uc1

\pard\cf1 Elem1\cf2 Hello \cf3 Elem2\par

2nd Liane : \cf3 Elem3\cf2\par

\cf3 Elem4\cf2 3rd\cf3 Elem5\cf2 Line : \cf3 Elem6\cf2\par

4th Line : \cf1 Elem7\cf0\par

}

Here is my regex :
(?<=\\cf[13] ).*?(?=\\cf.)


It's working just fine on those sites :https://regex101.com/ , https://www.regextester.com/ , https://regexr.com/
But not in Windev...

Do you have an idea why?
Thank you.

Hi Wahib,

probably because supported regex expressions in wlanguage are way less advanced than on these web sites.

You can certainly ask the support about the difference in behavior for a definite answer about it.

Best regards

Hi,

check out these links:

sText is string = [

ouicompat\deflang1033{\onttbl{\0\nil\charset0 Tahoma;}}

{\colortbl ;\

}
]

sRegex is string = "(?<=\\cf[13] ).*?(?=\\cf.)"
clMatches est un MatchCollection <- Regex.Matches(sText,sRegex)
POUR TOUT clMatch de clMatches
Trace(clMatch.value)
// POUR TOUT clGroup DE clMatch.groups
// Trace(tab + clGroup.value)
// FIN
FIN
