regexp issue

Thanks alot nml, that solved the issue. awyeah I could use your expression but I don't know how to place it I was afraid I might disturb the whole code when regsub is easy and safe to use or remove

Thanks once again awyeah and nml.

regexp issue

Well my idea was first to check with regexp to match the string and then proceed to substitute, you can substitute in many ways: regsub IS NOT the ONLY SOLUTION.

You can use nml's expression for regsub or use this then, lol:

Code:

set text [lindex [split $text] 0] Three Runs [lrange [split $text] 2 end]

This should also do the work for you, matches the two output strings you showed.

Untested, but I guess this should do the trick, based on your examples:

Code:

regsub -all {([[:digit:].]+) 3 ([[:alpha:]]+)} $text {\1 Three Runs \2} out

regexp issue

2007-09-15T10:57:33-04:00

Thanks for your reply awyeah but I dont think that will slve my problem ok let me tell you again, currently I am using this:

Code:

regsub -all { 3 } $text " Three Runs " text

That will make " 3 " into " Three Runs ", but I want some changes like:

If 3 has numbers before it and alphabet after it then make that " 3 " into " Three Runs "

For ex:

Code:

over 18.1 3 fuller over 19.4 3 This is a test

I want that " 3 " to be turned into Three Runs. So it will look like:

Code:

over 18.1 Three Runs fuller over 19.4 Three Runs This is a test

Thanks

Hi
like this:

11.6 3 test --> then turn 3 into Three

To match this you can use this:

Code:

#if $text is the string: "11.6 3 test"if {[regexp {^(([0-9.]{3,})|([0-9]{1,}))(\x20)(3)(\x20)([a-z]{1,})$} $text]} {#for substitution you can use regsub or string map#or you can do it this way:set text [split $text]set text [lindex $text 0] Three [lindex $text 2]

regexp issue

2007-09-15T00:46:00-04:00

Hi

Can you tell me how can I regexp a number which contains certain things before and after for ex:

I want to look for "3" but look for 3 only when 3 has a number before it and an alphabet after it and turn 3 into THREE.

like this

11.6 3 test --> then turn 3 into Three

Turn Number three into Alphabet Three

but

if it's number 3 number then return
or if it's alphabet 3 alphabet return

Thanks
