Regex 1

[Removed #5]

I'm fighting regular expressions - some seem straight forward - this one is giving me fits.
Desired replacement (vb.net regex.replace) for a string:

• begins with either a "("or a "["  [\(\[]
• possibly a space \s?
• probably a "v" v?
• possibly a space \s?
• possibly an integer  \d* <- the problem part
• possibly a period or space [\.\s]
• possibly another integer \d*
• possibly a space \s?
• then the closing ( or [  [\]\)]

so the regex should look like [\[\(]v?\s?\d*[\.\s]?\d*\s?[\)\]]

okay, so I left the initial space (2) out and changed the regex to [\[\(]\s?v?\s?\d*[\.\s]?\d*\s?[\)\]] which seems to work.  Why did it not present - until the first digits portion of the regex??
 
This is replacement text in the file name of a book, typically the "version" number of a scanned ebook so there will probably be text before or after the string to be replaced (for testing I'm doing a replace with a "$").
given as input:
 (22.5)
only (v 5.6) one
(v1.5)
some ( v .5 ) stuff
(v15)
 
and I'm getting:
$¶
only $ one ¶
$¶
some ( v .5 ) stuff¶
$¶

 

Any ideas what I'm doing wrong in there, cause I can't see it???

that is some very high quality gibberish you're enunciating there Pal

No, I figured out how to make it work like I wanted, I'm just not sure why the mismatch didn't appear till late in the string.
