is there a metacharacter for the space character ' ' in regex?
I went looking and thought the character class \s would help me find spaces, as its described as "matches any whitespace character" but on closer examination it is defined as the character set [\f\n\r\t\v]. Of the ones i'm not familiar with (\f = "form feed", \v = "vertical tab"), they couldn't also be masquerading as a space char, could they?
The book then gives an example of a pattern for a space or tab as [\t ], so presumably the literal ' ' character is fine? (I tried it in Dreamweaver's regex search and it worked, but is this a one-off, or is it a general rule?).
Just for completion, is there a metacharacter equivalent ?
Remark: its a bit surprising and randomly confusing that \s does not include the space character !!
Question: Maybe I'm missing something, so why would this be so?
