Hi all,


I'm having some problems generating the regular expression for "any
printable character except " between ". For example:
"hello, how are you"
"212 dasd 2"
"bugasd "


"" - SHOULD NOT WORK
" " - Can work!


I'm trying along the following lines:
identifier \"[[:print:]^\"]+\"


but it never works as I expect. Any ideas?


Cheers,


Paulo Matos
