10 posts in this topic

Try -> [^0-9.]

ah perfect!

thanks... so in this case is the period literal?

Dot is never special inside a character class, so [^0-9.] would work as well.

- [ ] (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.

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.

Are you sure? Try it:

ConsoleWrite(StringRegExpReplace("Microsoft Office Hotfix 4.5.24 BETA", "[^\d.]", "") & @LF)

Great!

You proved to me and gcue that there is more than one way to skin a cat.   :cheer:   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.

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") )

Where in the OP is there a slash?  (rhetorical question)

This is my last comment as this is no longer helping anyone.
