 Posted: Fri Jul 18, 2008 8:07 pm Post subject: RegEx help needed... - [Solved] |
 |
|
I am wanting to strip out several characters out of a string. I need to remove all
commas
periods
the word NULL
spaces
single & double quotes
left & right parenthesis
hyphens
from a string. I don't know RegEx expressions at all. I can do this with StringReplace, it just takes a LOT lines to do it, whereas I think this can be done with one RegEx statement.
Can someone offer some help on this? Can you try to break it down and explain what each component is so that I can learn and compare to the help file?
Thanks!

\W = any non-word characters
| = OR
(null)+ = all occurrences of the word "null"
| Code: | string = s,t.rnull 'i"(n)g-
MsgBox,% RegExReplace(string,"\W|(null)+") |
You could also replace \W with a bracketed list of the punctuation to remove, if other punctuation should be kept.

Exactly what I wanted!! Thanks! Instead of 8 lines of code or so, it's one.  Thanks for the explanation as well.

I should have added the i option as well, to make "null" case-insensitive, since you did have it in all caps. | Code: | string = s,t.rNull 'i"(n)g-
MsgBox,% RegExReplace(string,"i)\W|(null)+") |
