gcue 10 Posted April 3, 2014 ah perfect! thanks... so in this case is the period literal? Share this post Link to post Share on other sites

guinness 1,518 Posted April 3, 2014 - [ ] (though place at the end of the class is just fine e.g. [][]) and have to be escaped in a class. Unless jchd proves otherwise.

ZombieKillz 1 Posted April 3, 2014 (edited) After jchd's comment, it would only work if the string ended after the version number. If you have "Microsoft Office Hotfix 4.5.24 BETA", it would match " BETA" as well. Instead use this --> [^0-9.] Edit: gcue, To answer your question about the period being literal. If I understand the definition, then one period would be literal or one character or string but this reg expression is finding all periods and numbers in your string. Further to my point above, if you had other numbers and/or periods in your string then it will find those as well.

If you have "Microsoft Office Hotfix 4.5.24 BETA", it would match " BETA" as well. Are you sure?

ZombieKillz 1 Posted April 3, 2014 Great! You proved to me and gcue that there is more than one way to skin a cat. I used a regex tool I have and did not put the code into AutoIT (eww). I also proved that my original post ([^0-9.]) and my last one ([^0-9.]) works as well, now that I've put both into AutoIT ConsoleWrite as you've demonstrated.

mikell 1,010 Posted April 3, 2014 (edited) I also proved that my original post ([^0-9.]) and my last one ([^0-9.]) works as well The first one is good but not the last one which is made for checking the backslash too - as guinness noticed msgbox(0,"", StringRegExpReplace("Microsoft Office Hotfix 4.5.\24 BETA", "[^0-9\.]+", "$1") ) msgbox(0,"", StringRegExpReplace("Microsoft Office Hotfix 4.5.\24 BETA", "[^0-9\\.]+", "$1") ) Edited April 3, 2014 by mikell Share this post Link to post Share on other sites
ZombieKillz 1 Posted April 3, 2014 Where in the OP is there a slash? (rhetorical question) This is my last comment as this is no longer helping anyone. Share this post Link to post Share on other sites
